About 10 years ago I did t-shirts with a group of girls at church that were a kind of tie dye but I can't remember exactly what we did. It seems like we used magic markers or something to write on the shirts and then dropped alcohol on the spot which made it bleed or spread. It was cool and the girls enjoyed it. But it seems like that would wash out in the laundry and I know the shirt that I made did not wash out. Anybody done anything like that and can refresh my memory?
