For my 11 birthday we tie-dyed t-shirts. Fist I bought some dye at a craft store and I got some white t-shirts at a second-hand store. I told the girls who came to bring extra white things if
the wanted to do more.(socks,shorts,or more shirts) I got a lot of elastics at a craft store and divided them up between the girls.
When we were done we hung them all on the clothesline and everyone stood in front of their shirt and we took pictures which we gave to them after. Everyone went home happy with a great shirt!
