CatHat is worked in the round after a ribbed brim worked flat. The final opening is grafted (link to technique tutorial video in pattern), the bow with fabric lace edging is worked separately and sewn on afterwards.

You will need one skein of Lana Grossa Carezza = 140 m / 50 g or other yarn with comparable yardage, circular needles and a cable needle, a stitch marker, tapestry needle, fabric scissors, sewing needle with matching thread and a remnant of fabric lace.
