The Different Types of Yarn Fibers

By Alicia Kachmar – 10 Comments

When planning out a crochet project, in addition to choosing yarn colors, you have to take into account the texture and functionality of different yarn fibers. Even if they are both worsted weight, for instance, using a bamboo cotton compared to an acrylic will change how your project turns out. What kind of yarn fibers are out there? What are the differences? Here is a general breakdown:

Synthetic and artificial yarns consists of manmade fibers. Think giant Red Heart acrylic skeins that come in every color imaginable. While most synthetic yarns that I use are of the acrylic variety, there are also yarns made from nylon and polyester. Acrylic yarns are the result of highly involved chemical processes and are twisted as opposed to spun. They tend to be on the rougher and sometimes scratchier side (as opposed to cashmere and bamboo cotton), but yarn fiber technology has produced some softer varieties. Some benefits of synthetic yarns? They also tend to be cheaper than other types of yarn and come in a wide variety of colors.

A sub-category of synthetic yarns are the catch-all term “novelty yarns,” which are of the curly, furry and fuzzy varieties, or anything with a distinctive texture. They can even be multiple kinds of yarn woven together and take the idea of “multi-colored” to the next level. Boucle and eyelash yarn are two specific kinds of novelty yarns and can add a lot of texture to a project and may be well-suited for trims or accessories.



Naturally-derived yarns can come from two sources: animals and plants. Common animal-derived fibers are wool, silk, alpaca, cashmere and mohair. Wool yarns are good for those bulky winter projects where warmth is key, and luckily there are lots of not-scratchy options out there. It may cost you, however, as wool is spun from sheep and requires a process that relies on people not just machines. Just like buying garments in shops, fibers made from cashmere and mohair are pricey, but these types of yarn make for some elegant, extremely soft finished items. Unlike synthetics, natural animal fibers have “stretch” to them, which means they may alter when in contact with water. (Like when you felt with wool!)


Some common plant-derived fibers are cotton, hemp, soy and bamboo, and most recently there are organic varieties of these if you are a green crocheter. Just as with clothing made from them, these kinds of fibers wash well without being altered and they are more lightweight. Cotton yarns are good for making dishcloths and socks, for instance, and some organic varieties are almost as soft as mohair, lending themselves to crochet clothing projects.

Are there particular types of yarn you prefer to work with?

    I love to try new yarns and get sorely tempted when I visit Hobby Lobby or Michael’s – I love handling all that soft yarn! For the more expensive yarns, I look out for sales. Herrschner’s often has good sales on their yarns. There is also Smiley’s though their shipping charges and minimum make it better if you can combine an order with another friend or two. Both Hobby Lobby and Michael’s will sometimes have coupons. I always check for coupons before I finalize a purchase.

    @Christina, I actually made that potholder! I believe it’s just 15 rows of single crochet (ch 16) and then with a black single-crocheted border. I embroidered on the face with yarn, freehand.

    @Lorraine, I do sell some of the patterns you see above. Check out my bio post on here for links:
