Hey John....no dice at the craft store. They had lots of other neat potential materials that I grabbed, but no holographic material. If you're able to pick up those three colors for me it would be great. I can comp you back with some other material, flies, etc. If not, don't worry. I'll continue my search in other places, or grab some myself when I'm in that area.
Have fun with the kids this weekend. Thanks again for the gesture.
