Knit in a worsted weight washable yarn, this soft, squishy hat is form fitting and will stay on place on the head. The one by one ribbing draws in just enough to keep the hat snug. The pattern on the body of the hat is simple garter stitch interspersed with columns of knits to break up the pattern. the rest of the body knit plain until the top. I decreased quickly over a few rounds to finish off the hat.
