For my son’s first Christmas I crocheted him a couple festive hats for the season. The hat starts with a ribbed band created by crocheting short rows of single crochet, but using the back loops only (this is what creates the ribbing effect). Once that is joined to create the circular band, the rest of the hat is crocheted in the round using double crochet, and double crochet 2-together (or the decrease stitch).
