Interchangeable Hair Bows

I saw this great idea the other day on a hairbow that has a changeable center. So I decided to try and figure it out and make my own. Here is the one I made.
Spiffy huh. I removed the backs of the button cover and glued a small magnet to the back (I just cut up one of those sheet magnets you get on your phone book). Then I bought some small super strong magnets at Michaels and glued one to the center of my flower. Now I can change the center out depending on Amy's outfit. I can also use the centers with other hairbows. Now I just need to make her a few basic colors in hairbows and I'll be set. Pretty spiffy huh!
