Jewel hat (crochet version)

This is the little sister of the Jewel Hat, with the main difference being that the hat is 100% crochet construction. FpHdc and BpHdc create a ribbed brim and bobble stitches create clusters of jewel like shapes across the hat. Add a pom pom for extra enjoyment.

All terms are in US terms.
