Here's some info on how to make your own!
"For our proto, our designer actually hand sewed each sequin on by hand, and then left a space for the screen printed flower applique. She does not recommend doing that yourself! Luren suggests going to a fabric store and buying a small amount of sequined fabric, maybe the stretchy variety. This could be a little expensive, so another great alternative would be to find some sequined wonder of a dress at a thrift store for a couple of dollars. That way you would be recycling material and not spending much $$. The fabric can them be fixed onto a frame of canvas stretchers and decorated as you like."
