I would search the internet for the shirts or Michaels has them for $2 alot. Not sure if you have a Michael's in your area. Great idea but how would you judge how many would come and participate? Send a response home to see who would join in the fun?

Had an idea of a station set up at one of the yearly festivals where kids could come and design a t-shirt. Amount to charge would depend on the amount that has to be spent to get all the supplies. Would need to purchase in bulk some white t-shirts in different sizes, some paints, sponges, glitter. Not sure of iron-on items since the station would be set up outside, and that could be a burn hazard around the kids.
Can anyone share their opinion on this? Does anyone have any good ideas on where to get some shirts in bulk that wouldn't cost too much? Would like to keep the cost down so the shirts could be sold as cheap as possible.
