This pattern is a basic half double crochet basic beanie done in a spiral so there is no seam. Measurements are given for babies, kids, teens, womens and mens for daily use and for chemo caps. This pattern is for a variety of hook sizes and yarn types. You can change it to make your own designs but this is the basic pattern. Please “hook it” and let me know what you think. It takes about 2 hours to make. Get your old times table chart. This is one that you do not need a stitch marker but you may use one. Maybe you can use this to teach your girls and grandchildren their times tables. :P
