Some fashion fabrics, maybe at Joann's? Are covered in glitter type material and are very stiff and rough. I saw a ton of it in the fabric district in NYC. Didn't buy any though, wasn't my style. Have seen it on priject runway as well. It didn't seem to flake like normal glitter covered fabric, but it was stiff and maybe to sharp? I have even seen a slightly softer version in ribbon rolls at Walmart. This was about a year ago, I don't know if it's still around. Maybe a tulle type fabric would give a good slightly rough gritty texture? Sequin covered fabric? Check the prom fabric section at Joanne! Please let us know what you settle on. I'm excited to see this wonderful gift!
