I bought this product to customize shoes for school. You know, those white gym shoes that ALL children in the class have? My daughter made her own drawings (she is 8 years old). It's easy, it works as a felt, you just do a little more care to avoid drool. Normally it must go through eventually, but on the slippers, I did not. I have not yet tried on a tank top or something, but I think there are plenty of good ideas to find. What make cool creative workshops with small, meaningful if it is to decorate their everyday objects (they will remember every day that it is they that have done). That said, I would have preferred to have more color choices.
