This is a beanie incorporating the Art Deco diamond pattern from the Diamond Ray cowl. The hat is worked in the round using stranded colorwork. Instructions are included for both a sock weight version and a sport (or light worsted version), but you can play around with needle size and the number of 16-stitch repeats to create a similar hat with a bulkier or lighter yarn. Charted instructions, but not line-by-line written instructions, are provided for the colorwork body of the hat.
