This book features beginner based patterns by Scarlett Royale that also uses formulas to help you use any loom to create any of the 8 patterns. Great book for designers starting out. I used the 36, 42, and 48 peg KK replacement looms as written examples. They also have video tutorial links to help understand how the formula and pattern go together. The 8 patterns include beanie, slouch, cloche, ball cap, ski mask, flat cap, and beret.
