Shop by Yarn Weight
We've collected our yarns by weight. For the most part, yarns that are the same weight can be substituted for one another without affecting the size of the final project.
Average needle size, gauge, and amount needed per project are estimations and will vary depending on personal knitting style and the desired density of the finished fabric.
To learn more about yarn weights, see the Standard Yarn Weights page on the Craft Yarn Council webpage
