There are 6 sizes, one for each member of the family, from newborn to Dad’s and Grandpa’s. Easy pattern with embellishments that can be interchanged from hat to hat. You decide which embellishment you would like for your size hat you are making. This is such fun to create, you will want to make one for everyone in the family! Pattern uses worsted weight yarn, and knitting needles, US # 6 and # 8. These work up pretty fast so you can be thinking of whipping up a box full for Holiday gifts!!
