I saw a flower made out of a zipper in a lady's hair, but didn't take a picture of it. When I got home, I couldn't remember what it looked like, so I experimented and made two different ones.
The spiral one is easier to make. Both are sewed a little, and hot glued a little.
The spiral flower used up one side of a white 18" zipper.
The one with petals used up a little more than one 18" zipper.
Both together didn't quite use up 2 zippers.
