I know there is a crochet fish hat pattern out there. It is a perfectly good crochet fish hat. I've made her crochet fish hat. It really is a nice pattern.
That being said, I am not a fan of single crochet hats. They are fine, but I just really prefer the looser fit of a half double crochet hat. So, I sat down and started working a pattern up from scratch. I didn't just change the sc areas to hdc, I wrote an entirely different and new pattern.
