There are many types of yarn that you can choose from when you are crafting with yarn, be it crocheting, knitting & more. Yarn can be made of different fibers, weights and textures, as shown below.
When you are crocheting a project, it is essential to make sure you are picking the right yarn for the type of project you are making.
For example, if you crochet an acrylic potholder it will melt once it comes in contact with heat, so you will need to use 100% cotton instead, so it will hold up to the heat.
This is just one instance of why knowing about all the various types of yarn is important.
Scroll on down to learn about the types of fibers yarn can be made in such as animal, plant based and acrylics. All yarns are a different since they can be spun and mixed with different properties to create a unique blend as well as different weights of yarn.
You can look at the list below as well as a more detailed explanation.
What are the Types of Yarn Fibers?
Most fibers can be broken down into two categories: natural and synthetic.
- Natural fibers come from animals such as sheep or alpacas or are plant derived, such as cotton or bamboo. Different still, silk yarn is also a natural fiber yarn, but instead comes from the silkworm. Yarn made from animal fiber typically has much stricter care instructions.
- Synthetic fibers are those that are made up of various plastics. These plastics can range from the very common acrylic, to polyester, rayon or nylon. Synthetic yarns are easy to care for, including hassle-free washing and drying requirements.
There are also blended yarns that include a bit of both natural and manufactured. One of the more commonly found blended yarns is the acrylic & cotton blend. How much of each is up to the brand and manufacturer of the yarn, but they can range anywhere from 90/10 acrylic or 90/10 cotton.
Blended yarns are popular because they get to take advantage of each of the qualities of the different materials.

Merino wool is from merino sheep and is one of the softest wools. It is perfect for any type of project that will be next to the skin such as scarves, mittens, hats, and sweaters.
Merino wool yarn is washable, and able to withstand machine washing easily, so it’s perfect for everyday wear.
Wool yarn is made with the hair of sheep. Wool is warm as well as durable during use. It makes great sweaters, hats, scarves, and gloves. Some wool is rough or itchy at first, but gets softer with washing. Yarns made from an acrylic and wool blend are also very popular. It combines the softness of wool and the ease of use of acrylics.
Alpaca yarn is made with the hair from an Alpaca. This fiber is cozy and has a luxurious feel to it which makes it perfect for anything you create that will be close to the skin. It is one of the warmest fibers available and can also be blended with other fibers easily.
Bamboo yarn is made from bamboo plants and can be harvested without killing the plant which means it is eco-friendly. It is made from bamboo grass that has been extracted into cellulose and then spun into a silky smooth yarn.
This fiber is sheen and lightweight, which makes it great for Spring & Summer projects. The bamboos fibers are naturally silky soft and smooth – which makes the yarn incredibly soft for shawls, cardigans and more. It is often blended with other fibers for more texture and variety.

Fabric / T-Shirt
Fabric and or T-shirt yarn can be bought or made yourself using old cotton t-shirts or fabric scraps. Since this yarn will vary depending on the fabric it was made with, you will need to test out different crochet hooks to see which one would work best.
One of the most common fibers used to create yarn is acrylic. Acrylic yarn is made with chemicals such as petroleum, which means it is a fossil fuel-based fiber. Learn more about how acrylic fiber is made and see if it is a good choice for you.
Since acrylic fiber is easily produced, it is usually inexpensive. You can find this yarn at most stores without any trouble. A few easy to find ones are Red Heart Soft and Red Heart Super Saver both of which are budget-friendly.
Cotton thread fiber is commonly used for lace projects and filet crochet patterns. It is a superfine 1 weight yarn that is inexpensive and can be found at most local craft stores.
