Hello, I completely understand how difficult it can be to select the right yarn, especially when shopping online. As yarn thickness varies within each weight category, we recommend checking the gauge on our site before purchasing. If you have a sock yarn you really like working with, I'd be happy to help you find a sock yarn that is a comparable thickness. Please reach out to me at customerservice@yarn.com I want to be sure you get the perfect yarn for your next project! Best wishes, Brianna Customer Service Team WEBS® / America's Yarn Store®
