Here's another hat using the Carons Simply Soft yarn.
I wanted to do something with this diamond pattern. The diamonds require a base that's divisible by 8, but I didn't want to do my usual crown in solid single or double crochet, so I experimented with something more open and ended up using a series of V stitches and shells. I'm rather pleased with how it turns out. The diamond pattern makes for a hat that's more decorative then warming, though!
