Crochet Cake

My sister in-law does a lot of crochet work and she is amazing! She's made a ton of these cute flowers that you can put on hats and headbands or whatever (hence the flowers). Here is her etsy link http://www.etsy.com/shop/forumyonly1. She also makes hats, skirts, toys, and probably whatever else you can think of. I wish I had had something to roll the fondant on to make it have some sort of crochet pattern. That would have been cool. Can you tell it's a skirt on top? My kids thought it was a volcano.
