This hat was made to use up some of the scraps in my huge yarn stash. One color was from my oldest daughter's sweater, another from a shawl I made for my friend, the rest from a patchwork garter stitch blanket I made. It is a quick and fun knit, and (if you're like me), you already have enough yarn laying around so you don't have to buy any! BASIC SKILLS NECESSARY Knit on circular (16') and double-pointed needles. GAUGE 15.5 sts = 4 inches. SIZING / FINISHED MEASUREMENTS Fits a 21-23 inch adult or teen head.
