Finished size: 8” long x 10” across bottom.

Pattern from https://www.willowyarns.com/frostbite-caps-crochet-patter...

I followed the pattern except for R11, which isn’t written correctly. It should say:

Rnd 11: Ch 1, working in back bump of hdc from previous rnd, sc in same st as join and in each st around, sl st to first sc to join.

Also, I did the 5dc cluster a bit differently (to make them pop a little bit more) as follows:
5-dc cluster: Yo, insert hook in indicated st, yo, pull through 2 lps, (yo, insert hook in same st, yo pull through 2 lps) 4 times, yo, pull through 5 lps on hook, yo, pull through last 2 lps on hook.
