I ordered the small sized, 2-color, fold up brim hat. I love it! It fits perfectly! My head circumference = 20 3/4". I ran out of white yarn midway through chart 4 and received a quick reply that more yarn will be on the way. Great customer care and service. I asked several questions when I started and they were all answered super fast. I would recommend this hat kit to anyone! It is a fun knit. 5 Stars!
