The Best Sock Yarn Weights: What You Need to Know

What is Sock Weight?

Sock yarn is versatile, and can be used to make hats, cowls, lacy shawls, toys, and even a yarn blanket. The yarn material used in sock yarn is very thin, and 4ply is the name the sock yarn is sold under. Coming in either 100g or 50g, it is usually sold in skeins or balls. It is wise to confirm the length of the measurements because it ensures accurate yarn weights. For example, 100g of sock yarn should come in as 400m.

4. Eco-Friendly Yarn Options:

Align yarn crafts with eco-friendly practices by selecting cotton or bamboo. These types of yarn are not only high quality, but durable.


- Organic Cotton: Grown without harmful pesticides, organic cotton is soft and gentle on the environment. The cons of using organic cotton are that it holds onto moisture longer, and you are more likely to have cold or wet material on the body. If you craft a sock, the sock may droop or stretch over time due to less memory. Despite its drawbacks, organic cotton yarn is great for making hats, towels, stuffed toys sweaters, and more.
