I mentioned this to my other half, along with filling in some of the
background on what all you guys were trying to do, and she said, if you
want to find some of that material, just go to any "retro" clothing store--
that they oughta be able to fix you right up. She also said something about
"transfer paper" being available at the majorly large craft stores
("Michael's" being one around here), I dunno if that has been considered or
not, though she did say it was expensive.

Hope this helps...
