How to Determine Yarn Thickness

Are you tired of guessing which yarn to use for your next knitting project? Well, fret no more, the easy steps below will tell you immediately which weight yarn you are holding. Whether you’re a beginner or an experienced knitter, understanding yarn weight is essential for achieving the desired results in your projects.
