Crochet Flowers...

I've been playing with yarn a bit this afternoon, trying to find a good crochet flower that would work on cards. I'd still love to find something smaller.  If anyone has a link to one that's small (and easy) I would love it if you'd share! These are the three types I tried (haven't added buttons or anything to them yet):

This, of course, is my favorite. I may just use this one on a project soon.
