Different Types of Yarn: Explained

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 before starting a knit or crochet yarn project.

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 following.

What are the Types of Yarn Fibers?

Most types of yarn 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.

Note: 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. You will find other blended yarns such as wool mixed with acrylic and more.

Types of Yarn for Crochet

You can crochet with any type of yarn. The type of yarn you choose to crochet your project with is determined by what each type of yarn is good for, which was described above in great detail.

I like to use 100% cotton or an acrylic blend when crocheting most of my projects. Acrylic blends are fantastic for blankets, while cotton (or cotton blend) yarns are typically reserved for projects such as hotpads or washcloths.

If you are new to crocheting, I would suggest buying an acrylic blend yarn that is either a 4 (medium) or 5 (bulky) weight yarn. Yarn of this size (which I get into more detail below), is easier to hold and see the stitches with.

Pro-tip: Don’t crochet with black or very dark yarn if you are just beginning… it is very hard to see the individual stitches and you will become frustrated almost immediately!

Types of Yarn Weights

Yarn thickness is used to determine the weight of the yarn. Use the yarn weight chart below as a guide to determine how and when you should use each type of yarn.

The yarn weights explained below are based on the CYC Standard weight System.

Weight #0 or Lace includes yarn type fingering 10-count crochet thread. This weight of yarn is usually crocheted using the US hook size of 6/7/8 (steel) and B-1 of regular. The metric equivalent is 1.6-1.4 mm for steel and the regular metric hook size of 2.25 mm.

Weight #2 or Fine includes yarn types of sport and baby. This weight of yarn is typically crocheted using the US hook sizes of E-4 to 7 and the metric sizes of 3.5 – 4.5 mm.

Weight #3 or Light yarn includes the yarn types of DK and light worsted. This weight of yarn is usually crocheted using the US hook sizes of 7 to I-9 and the metric sizes of 4.5 – 5.5 mm

Weight #4 or Medium yarn includes the yarn types of worsted, afghan and aran. Worsted weight yarn is usually crocheted using the US hook sizes of I-9 to K-10 1/2 and the metric sizes of 5.5 – 6.5 mm.
