For these patterns you only need to know how to make a chain, single crochet, half double crochet, and double crochet. Included in the ebook is 2 patterns. One for a Blythe brim beanie and one for a Blythe crochet helmet. Also included is a link to a set of videos that walk you step by step through both patterns. My email address is also included so that you can ask as many questions as you need. I love to help!
Any hats that you make from this pattern can be sold as long as you credit me as the designer. Thanks!
