Where can I buy undyed worsted weight superwash yarn

does anyone know of a coop or inexpensive place to purchase undyed worsted weight superwash yarn - it can be a nylon blend or just superwash but I’d like a worsted weight for kiddos socks so they knit up quicker!

At Knitpicks:

You might also be able to find some on Etsy.

Awesome! thank you! and at a really reasonable price too! Thanks!

Its good yarn too. I just ordered A LOT of it to dye!
