The first are a crowns!
There are 3 rounds of sc, to whatever length you want it to be. The peaks of the boys crown are 2 hdc, ch 2, 2 hdc in the same stitch. Where the girls crown has a pattern of the smaller peaks, and larger peaks that are 3 dc, ch 2, 3 dc.
I made them big enough to fit bigger babies, and can be pinned to fit the smaller babies.
All the monkey ears are, 12 sc in a magic ring, sc once in each stitch around round 2, and for round 3, sc in front loop only... but not in all of the stitches. Maybe 9 or 10, leaving the others open to sew onto the hat.
