Now that I made 2 more Kitty hats, I remember now how I did the bow! So, I wanted to share the pattern.
Crochet Bow pattern
This was done with worsted weight yarn, in this case Red Heart Super Saver in Dark Orchid, and a size H hook.

Round 1: 8 sc in 2nd chain from hook. Sl st in 1st st. Ch 1.
Round 2: 2 sc in each stitch. (16) Sl st in 1 st. Ch 1.
