Ok, so I sitting there looking at my kids fun foam sheets and I started thinking, hmmmmmmmm. I should try to run this through the cuttlebug using Stampin' Up! dies. Well, I am so addicted!!! These can be interchangable. The only thing that bothers me is that the brads are not long enough to go through several layers of the foam. But you can prepare a bunch of these and mix and match them with your outfits!
