My daughter needed to bring a shirt to preschool to tie-dye. My first thought was to go out to Hobby Lobby and buy one, but then I realized she had a white shirt that had a stain on it that would be perfect to use. She took the stained white shirt to school and sure enough came home with an awesome tie-dyed shirt! It looked GREAT, you couldn’t even see the stain and it cost me NOTHING! That is my kind of savings! To get instructions on how to tie-dye, check out this article.
