I think a crochet hat pattern made with seashell stitch looks very nice. Different colors or rainbow or single color. It looks beautiful with all kinds of colors. Red heart super ombre yarn and 5 mm crochet hook were used when making this crochet hat. Since it is an easy crochet pattern, it will appeal to everyone. Since it will not be very difficult for you to memorize how to do shell stitches, you will be able to work in the colors you want.
