We get lots of requests for this hat pattern! Don’t let this pattern fool you, it is not as difficult as it seems. You must follow the pattern, row by row, and then it will be very easy to do. The bubbles add cuteness to the fun leftover yarn stripes! We love our color scheme; you can chose your own colors and use up scrap yarns! Your friends will want this one too! Uses worsted weight yarns, and knitting needles, US #9, in 16 circular needle. Use size K crochet hook for optional tassel. We ask you to add it! It really makes the hat! One size fits most people.
