I found this flower pattern over at Lacy Crochet blog. She calls them swirl flowers. You can make them quickly, and as large or small as you like. It's a long chain, with clusters of double crochets.
Another point of interest on this: a couple of year ago I tried to make a hat, using Julia's hat as a pattern. But I hadn't been crocheting very long, and just couldn't figure out the patterned part. I made a hat using straight double crochet on all rows. But this time -- after crocheting more complicated items for a year or so, I could look at the hat and discern easily what the maker had done, and replicate it. It's fun to realize that you're making progress in your skills.
