Lunares is a simple slouchy hat with a fair isle border. It is available in three sizes and can be worn by both men and women. I used Malabrigo Rios for this design, but there are so many other wonderful worsted weight options out there. You will need a full skein of the MC, but probably only a half skein or less of the CC. When working the hem, I just picked up a stitch in every cast-on stitch. You could do a provisional cast-on instead and make those stitches “live” on an additional needle to complete the hem.
