I made this free form pin in 20 minutes. I was missing a black one I made long ago that I gave to my sister in law. This one is made with metal teeth and I used a jacket zipper. I left the pull on for interest. The other was made with large black plastic teeth for a jacket. These are really fun to make. I may teach this type for the Flower Power workshop at FabMo on October 29....not sure yet because there is are so many different kinds to teach...paper flowers, fabric flowers, felted flowers......etc.
