Pattern: "Starburst Flower Square" by SmoothFox.
This square is easier to crochet than it looks. Since I used my size J hook, I left off a solid round of double crochet that was in the pattern so that it would measure 12". It looks more like a cog or something to me than a flower since the center is only one color and the little spokes are kind of squared off. I like it!
