What about that idea with the flour/water thing. Someone took flour and water and mixed it up into a thick paste. They put it in a squirt bottle and made a Mickey design on their tee shirts. Then they put the shirts out in the sun to dry. Then they took fabric paint that sprays and sprayed it over the Mickey head, and let that dry. Then they picked off the flour water paste and underneath the shirts were white. It looks totally cool and I'm definately making myself one for next time. Hopefully someone will post a link to the directions. These seem easy enough to make.
