1. Wool

Wool is available from many different animals, which creates a variety of textures for the knitter as they work on their projects. Sheep’s wool is one of the most common types that people use in crafting because of its exceptional softness and versatility. Wool provides warmth without overheating when used appropriately, making it perfect for winter sweaters or scarves during cooler months.

These yarns dye into color transitioning yarn pretty effortlessly.

Properties of Wool

Wool is warm, soft, and durable
Boasts a lot of elasticity, so you can create less rigid projects like scarves or blankets with ease (great for beginners!)
Yarn made from this material is light and quick to dry
It’s not recommended that you use wool yarn if you’re allergic!

Wool Blends

Wool blends consist of two or more differently spun fibers combined. The most common blend contains at least 50% wool, but there are also blends that contain synthetic materials. These blends are mostly used for warmer garments such as sweaters because they retain body heat more effectively than pure wool yarns.

Types of Wool Yarn

There are different types of wool yarn, and each one is suitable for a different kind of project. The most common ones according to type are:

Medium-weight, heavy-worsted, and bulky yarns have a thickness that ranges between 12 stitches per 25 grams (superfine) and 15 stitches per 125 grams (bulky). These kinds of yarns work well for creating both fine and thick garments.

Manufacturers classify the different types of wool yarn by the percentage of wool content:

25% Wool

This type has a light texture, but it is not very durable, so it is best used for decorative purposes rather than wearable items.

50% Wool

This blend has a slightly rough feeling with an uneven surface due to its low luster. The durability of this blend withstands frequent usage.

75% Wool

This is the softest kind of wool yarn, which generates more heat when worn during winter months. It’s easy to maintain because dirt does not stick to it. This is a perfect yarn for knitting chunky blankets if you have the big blanket knitting needles.

Wool possesses an exceptional property known as the heat of wetting. When wool gets wet, it generates heat as the fibers release stored energy.

Advantages of Using Wool Yarns

Soft, warm, and durable
Hypoallergenic, so they work well for people with sensitive skin or allergies to most other types of yarn
Natural fiber which means it’s environmentally friendly
Boasts natural elasticity making them easy to care for
Water-resistant, thus repels moisture while maintaining its shape instead of becoming limp or heavy
Protects against cold weather conditions and keeps feet from getting sweaty on hot summer days
Flame-retardant, which reduces the risk of fires spreading. The higher percentage of wool in the yarn results in more fire protection.

Drawbacks of Using Wool Yarn

Doesn’t have as much shine or luster as synthetic fabrics
Scratches easily
Needs regular mending because the fabric deteriorates quickly in damaged areas if not repaired properly
Requires cleaning with soap and water, which takes about 15 minutes once you finish knitting your project

Uses of Wool Yarn

Wool yarn is commonly used in knitting and weaving. It makes garments, blankets, rugs, and more. Because wool provides warmth in winter and remains cool in summer, wool yarns are also regarded as the best yarn for slippers.

2. Merino Wool

Merino wool yarn comes from merino sheep and is finer than standard wool. The fiber diameter of merino wool ranges from 15 to 24 microns. This fine diameter makes it exceptionally soft against the skin, eliminating the itchiness associated with coarser wool varieties.

Merino wool is popular in clothing because of its softness and resistance to shrinking. It is more difficult to work with than other types of wool because it doesn’t stretch as much, which makes it less elastic when knitted into a garment. Additionally, fewer colors are available for this type of wool yarn compared to synthetic alternatives.

Properties of Merino Wool

More durable than silk and other natural yarns
Easy to care for (machine washable)
Standard weight: 100 grams yields approximately 175 yards; Heavyweight: 140 grams yields approximately 210 yards; Light Weight: 50 grams yields approximately 104 yards

Advantages of Using Merino Wool

No allergic reactions or itchiness due to fine fiber diameter (under 24 microns)
Durable and retains its shape after washing
Knitted items retain their shape quite well over time

Drawbacks of Using Merino Wool

Prone to pilling
Few naturally white yarns are available
Less elastic than other wool types because it doesn’t stretch as much

Uses of Merino Wool

Winter clothing including base layers and mid-layers
Shawls and outerwear garments that require durability due to frequent exposure or wear

3. Cotton

Cotton is one of the most popular yarn types. It’s very soft and breathable, which makes it perfect for warmer weather projects like summer sweaters. Cotton has excellent drape, so it’s ideal for clothes that are flowy or loose-fitting. You can make cotton yarns yourselves if you own the best beginner spinning wheel.

Properties of Cotton

Soft and breathable with high moisture absorption
Has excellent drape, which makes it perfect for looser fitting clothing
Readily available anywhere from grocery stores to yarn specialty stores
Machine washable and dryer safe
Holds up well in humid climates when taken care of properly

Advantages of Using Cotton Yarn

Easy to care for, making it a good choice for beginners
Readily available at cotton clothing stores and grocery stores
Excellent moisture management with a moisture regain of 8.5%
Affordable compared to luxury fibers

Drawbacks of Using Cotton Yarn

Prone to pilling
Gets tangled easily in knitting or crochet projects because the fibers are quite loose. You may need extra tools such as stitch holders or locking rings to keep things manageable.
Doesn’t hold tension well since the yarn is generally no thicker than a thread, so you may need more yarn for the same size project

Uses of Cotton Yarn

Cotton yarn is best for projects with short rows and small stitches such as afghans, scarves, dishcloths, and heat resistant batting for placemats. The loose fibers make it difficult to work on large knitting or crochet projects requiring tight stitching.

4. Acrylic

Acrylic yarn is a popular synthetic option. It is inexpensive and comes in a wide variety of colors, which makes it ideal for novice knitters or crocheters who are trying to save money on materials. It is also an excellent candidate for the best yarn for placemats. Acrylic yarns are not as durable as wool, but they are machine washable and dried easily, making them great for kids’ clothes that need frequent washing.

Properties of Acrylic Yarn

Comes in bright colors, making it great for children’s clothing projects or baby blankets
Machine washable and dried easily, which makes it ideal for larger items that get more wear like sweaters
Not as durable as wool; needles smaller than size 13 will split the yarn and create holes
Inexpensive, so first-time knitters/crocheters often choose it to save money on materials
Comes in just about any color imaginable

Advantages of Using Acrylic Yarn

Machine washable and dried
Available in just about any color imaginable
Resistant to bugs, chemicals, oils, and other external elements

Drawbacks of Using Acrylic Yarn

Not as durable as wool yarns
Needles smaller than size 13 will split the yarn and create holes through it. This is especially important for items that get a lot of wear, like sweaters made with acrylic yarn, because over time the item will start to fall apart if the needle size isn’t appropriate.
Doesn’t have the same “hand” (feel) as other fibers such as cotton or linen, which some people prefer
More expensive than some other types of yarns due to manufacturing costs

Uses of Acrylic Yarn

Acrylic yarn is perfect for making sweaters, blankets, and other wearable items.

It also works well for home decor such as pillows or curtains since it is not fragile like wool yarns.

Knitted items made with acrylic yarn include sweaters, blankets, scarves, and shawls.

Crocheted items made with acrylic yarn include scarves, hats (with ear flap), and pillow covers.

5. Alpaca

Alpaca fiber has been used for centuries by people in mountainous regions. Alpacas are well adapted to these climates with their thick wool coats, which protect them from freezing temperatures and provide insulation against the sun’s rays during warmer months. Alpaca yarn comes in a variety of weights and colors that mimic natural sheep’s wool but without lanolin or harsh chemicals that might irritate sensitive skin.

Properties of Alpaca Yarn

Sourced from alpaca animals like wool, but alpaca yarn is not itchy due to its smoother fiber surface
Has a soft texture and creates warm fabric suitable for sweaters or cardigans for winter wear
Tends to felt, so avoid machine washing; alpaca fiber ranges from 18 to 25 microns in diameter

Advantages of Using Alpaca Yarn

Soft texture that makes it warm and comfortable to wear
Fast-drying, making it convenient for quick knit or crochet projects
Not prone to fuzzing like wool yarns are
Luxurious yarn with an expensive price tag (but worth the investment)

Drawbacks of Using Alpaca Yarn

Not widely available compared to wool or acrylic
Not biodegradable due to the processing methods used
Too soft and fuzzy for sewing because it doesn’t have a firm structure

Uses of Alpaca

Alpaca is similar to wool but costs more. Common projects include:

Knitted items made with alpaca yarn include scarves, sweaters, shawls, blankets, and mittens.

Crocheted items made with alpaca yarn include ties or belts.

6. Cashmere

Cashmere yarn comes from cashmere goats. It is expensive, but knitted or crocheted projects made with this fiber last longer than those created with wool. Cashmere is softer than wool, so finished projects feel lighter on the body. Take care when washing these items by hand—always use cold water and dry flat to prevent felting.

Properties of Cashmere Yarn

Soft and lightweight fabric that is luxurious and expensive but worth the investment for long-lasting projects
Not as durable or eco-friendly as wool; cashmere requires dry cleaning
Too soft for sewing because of its flimsy structure
Cashmere fiber diameter must not exceed 19 microns per U.S. Wool Products Labeling Act standards, with no more than 3% of fibers exceeding 30 microns

Advantages of Using Cashmere Yarn

Exceptional softness and lightweight warmth
The fiber is really fine—approximately 6 times the diameter of a human hair
Luxurious feel that improves with age when properly cared for

Drawbacks of Using Cashmere Yarn

Too soft for sewing because of its flimsy structure. It can shrink over time, making projects more prone to holes than those created with wool.
Lacks the durability of other yarn types like lambswool or sheep’s wool. It’s not ideal for heavy-duty work since its delicate nature won’t resist the wear and tear associated with such projects.
Doesn’t have the same “hand” (feel) as other fibers such as cotton or linen, which some people prefer
Due to its high level of softness and lack of elasticity, maintaining tension when knitting or crocheting with this material is difficult. This usually results in loose stitches that are more prone to fraying over time.
More expensive than other types of yarns

Uses of Cashmere Yarn

Common uses include jumpers, scarves, socks, and other luxury garments.

7. Hemp

Hemp fiber comes from hemp plants grown in many different climates. It is environmentally friendly—the plant conserves resources because it doesn’t require much fertilizer or pesticide use while growing. Hemp is strong and sturdy but offers flexibility when knitting stitches, so finished items look good without feeling too stiff against the skin. Hemp yarn will likely shrink when put into a hot dryer or washing machine, and it’s not colorfast, so you might notice some bleeding of colors.

Properties of Hemp Yarn

One of the strongest natural fibers in the world
Sturdy and flexible with a texture similar to linen
Doesn’t require much pesticide or fertilizer to grow
Won’t shrink in the washing machine, but will change size when dried over high heat since hemp is not colorfast

Advantages of Using Hemp Yarn

Natural fiber with minimal environmental impact
Much softer than jute when compared directly
The fabric created from hemp yarn is breathable, keeping you cool in summer and warm in winter

Drawbacks of Using Hemp Yarn

Hemp yarn is not as elastic as other types. If you’re knitting tight, there might be pulling across stitches. Though it doesn’t pill like wool, the natural oil (lanolin) in some fibers could cause buildup that may lead to skin irritation.
Much more expensive than synthetic or cheaper natural fibers like cotton and jute, which can cost anywhere from $0.75 to $11 per kilo depending on quality
The fiber loops are not as tight in hemp, so there’s a greater chance of tangling during knitting. This could cause frustration when trying different stitches because of how rough hemp feels against your fingers.
Has a tendency to “grow” after washing if dried over high heat. Each time you use, wash, and dry it, the size will change even though the weight may be consistent.

Uses of Hemp Yarn

Common uses include scrubbies, coats, and home textiles.

8. Bamboo

Bamboo yarn is usually composed of a blend of bamboo and cotton or wool.

It’s more durable than synthetic fibers. The fiber loops are tight, which can make it difficult to get through each stitch without pulling on the fabric too much.

Properties of Bamboo Yarn

Plant-sourced from one of the fastest growing woody plants, reaching up to 35 meters tall
Fantastic drape property for flowing garments
Mechanically produced bamboo linen has a silky touch and is softer than silk in fine counts

Advantages of Using Bamboo Yarn

Hypoallergenic and gentle on sensitive skin
Doesn’t shrink when washed and dried properly
Impeccable softness that improves with handling

Drawbacks of Using Bamboo Yarn

Can pill if you’re not careful with storage or wear—the fabric creates little fibers on its surface, which can be bothersome for some people

Bamboo Yarn Uses

Different types of scarves, sweaters, hats, and more
Bags and purses sometimes use bamboo yarn because of its durability without any finishing touches
Scrubbies (if blended with wool), coats, and various other projects

9. Silk

Silk is the best-known type of yarn from centuries ago when considering strength. Silk yarn is smooth and has a lustrous finish. It’s not as durable as wool or acrylic, but its softness is unmatched. Before the invention of nylon yarns, silk was the go-to choice for knitting strong and shiny clothes.

Properties of Silk

Lightweight with excellent strength-to-weight ratio
Soft to the touch with a luxurious feel
Strongest natural fiber available
Highly lustrous with a natural sheen
Expensive due to limited production

Advantages of Using Silk Yarn

Maintains its shape without any finishing touches (no blocking required). Silk knitting projects finished with no additional steps look more professional than those made from other types of yarns.
Contains natural proteins that give the fabric durability over time while being very flexible when knitted into different shapes
Exceptionally lustrous with a beautiful drape

Drawbacks of Using Silk Yarn

Not as durable as wool yarns for heavy-use items
Needles smaller than size 13 will split the yarn and create holes. This is especially important for items that get a lot of wear, like sweaters made with silk yarn, because over time the item will start to fall apart if the needle size isn’t appropriate.
Doesn’t have the same “hand” (feel) as other fibers such as cotton or linen, which some people prefer
More expensive than other types of yarns due to limited production

Silk Yarn Uses

Silk is perfect for luxurious items including scarves, sweaters, and any fabric that needs an elegant feel. Some people find it difficult to knit with because it can be slippery to keep track of when working quickly.

10. Mohair

Mohair yarn comes from the Angora goat. This yarn is pricier than wool since it comes from a less available animal. Mohair fiber ranges from 25 to 45 micrometers in diameter, with finer hair from younger animals used for scarves and shawls, while coarser hair from older animals serves for carpets and heavy fabrics.

Properties of Mohair Yarn

Durable when knitted into fabric
Soft and luxurious to the touch, lightweight allowing for garments that need movement or stretch
Gentle on people with skin sensitivities because it doesn’t produce allergic reactions or itchiness
Easy hand-dyeing properties due to excellent dye absorption
Sports a great degree of luster from how the fibers reflect light

Advantages of Using Mohair Yarn

Warm and lightweight simultaneously
Good for sensitive skin as it’s not prickly like other yarns made from animal hair
Has significantly less pilling than other types of wool yarns because the hair follicles are much tighter together

Drawbacks of Using Mohair Yarn

Not as durable in yarn form and should be used carefully
Has a tendency to mat—it doesn’t have a lot of bounce back after being knitted or crocheted
Typically more expensive because it’s normally imported

Uses of Mohair Yarn

Common uses include wall fabrics, gloves, hats, carpets, and other home furnishings.

What Are Yarn Weights?

Yarn weight describes how thick or thin a yarn strand is. It’s also known as yarn count. Yarn thickness ranges from heavy-worsted, which tends to be on the thicker side, to sporty and very lightweight fingering yarns. The thinner yarns are typically easier for beginners because they’re less likely to cause frustration when working with more intricate stitches.

If you don’t know the yarn count of the yarn you have, use this yarn count calculator and converter to determine the yarn count!

Yarn Weight Categories

Manufacturers categorize yarn weights based on thickness, measured in stitches per inch (SPI).

Super Bulky Yarns

These yarns have a weight of heavy worsted or heavier and generally measure between 11 and 13 stitches per inch (SPI).

Chunky Yarns

Yarn in this category measures 14 to 22 SPI. This weight works well for making quick and cozy throws or more substantial garments.

Bulky Yarns

Yarn in this weight range measures between 23 and 27 SPI, making it a great choice for large projects like rugs, afghans, and sweaters.

Jumbo Yarns

These yarns have a weight of chunky and generally measure between 28 and 32 SPI. This category is best for large projects that require more than one skein, like blankets or sweaters.

Super Jumbo Yarns

Yarn in this weight range has a thickness of heavy worsted and measures 33 to 36 SPI. The higher stitch-per-inch measurement makes it a good choice for cable and other textured patterns.

Worsted Yarns

This type of yarn is generally used for medium-weight sweaters, socks, hats, scarves, or any project where the end result needs to be durable but not too heavy.

Sportweight Yarns

These are thinner than worsted yarns and therefore have more drape. This category is best suited for light garments and accessories such as shawls, scarves, hats, or sweaters that require a lot of stretch.

Fingering Weight Yarn

These are thinner still than sport weights and work well on projects like socks, gloves, baby clothes where you need the maneuverability to achieve a lot of different stitches.

Lace Yarn

These are the thinnest, most delicate weight category. Use them only for knitted or crocheted items where you need a very lightweight fabric that still has body to it, like shawls, scarves, and lace tops.

What Does Yarn Ply Mean?

Ply describes the number of strands twisted together to form yarn. Generally, the more plies there are, the thicker and stronger the yarn will be.

A 4-ply yarn consists of four strands twisted together.

The final thickness of the yarn depends on the individual fiber thickness (micronaire value) and the twist level. Therefore, a 4-ply yarn can have the same resultant thickness as a 2-ply yarn if the individual fibers are thinner or the twist is looser.

Choosing the Right Yarn Size

Yarns are often sold in specific quantities or ball sizes. A standard knitting ball of yarn is 220 yards, which is enough for a single sweater using average gauge.

To get different yardage options, you can buy several balls at once (more expensive per yard but lasting longer) or buy yarn in different quantities.

A skein of yarn is typically 500 yards, which provides enough for a scarf on average gauge with room to spare.

For more yardage, buy yarn by the cone or bolt. A standard yarn cone is 250 yards, whereas a regular cloth-based knitting bolt measures around 600 yards.

A yarn spool offers a lot of space for knitting projects, containing anywhere from 1,000 to 2,400 yards depending on the size. The downside is that it’s often more expensive than buying by cone or bolt, which can also be inconvenient if you don’t have a yarn winder.

Understanding Yarn Ball Labels

The label on a yarn ball indicates the following information:

Yarn Weight and Type

The weight of the yarn and whether it’s wool, acrylic, cotton blend, or other fiber content appears on the label. Yarn weights are typically represented by numbers from 0 to 12, with 12 being the heaviest and anything below being considered light in gauge.

Blend Percentage

Blended yarns indicate what percentage of the yarn comes from different fiber content. For example, “Wool 65% Acrylic 35%” means more wool than acrylic, while “Acrylic 70% Wool 30%” means the opposite.

Yarn Length

The length of the yarn appears on the label, usually written as “100g/200m” indicating the weight and corresponding length.

Ideal Needle Size

The label indicates the recommended needle size for knitting or crocheting with that yarn.

Yarn Gauge Specification

Yarn gauge is defined as the number of stitches per inch. You can find this specification in the middle or bottom edge of most balls for easy reference when knitting, crocheting, or doing other needle art projects.

Application

The yarn’s applications may be listed, including weft knitting, warp weaving, crocheting, and other crafts like basket-weaving or macrame.

Care Instructions

Care instructions appear on the yarn ball label. Whether you should machine wash the item is a major concern here.

Country of Manufacturer

The country where the yarn is manufactured and the copyright holder appear on the yarn ball label.

Things to Look for While Buying Yarn

Yarn Weight

Yarn weight depends on your project. Knitting a sweater for an infant with bulky yarn takes less time than using worsted weight.

Yarn Type

Different types of yarn have different weights and qualities. Choose wisely based on your project requirements. Examine each category closely before deciding on the right yarn.

Fiber Content

If you’re targeting a blended yarn, be aware of the different fibers and what they produce when spun into yarn. For example, if you’re looking for wool that drapes well, a blend with silk or alpaca won’t work because it won’t have enough elasticity.

Yarn Structure

The structure of yarn is just as important as the type. There are three different structures to consider when buying yarn: single, ply, and twisted (plied). Single-ply yarn is heavier in weight than a plied yarn.

Texture of the Yarn Surface

The texture of the yarn’s surface varies depending on how it was spun, what material the fibers are made from, and even its washing process. Choose according to your desired look.

Color of the Yarn

If you don’t plan to dye your knitted items, the color of yarn influences how they look. Lighter colors such as white and light gray are great for projects like baby blankets, while more vibrant colors are perfect for trendy scarves.

Yarn Care Instructions

Be aware of whether the yarn you are buying is machine washable or not. Otherwise, all your hard work may go in vain.

Brand Name

More popular brands guarantee a good quality product, while lesser-known companies often produce subpar products.
