You will need:
a denim shirt
I start by binding the sleeves first. There is no correct way to do this, but I like to keep it in an accordion-like fashion. After the sleeves are tied (with the rubber bands), crumple the body of the shirt in a bundle and reinforce with extra rubber bands. Pour 3 quarts of bleach and 3 quarts of water into a plastic container. Using rubber or plastic gloves, place the shirt into the bleach mixture. Let the shirt sit, completely submerged for approximately 15-20 minutes (I did it for 15). As soon as the color starts to lighten, remove it from the bleach. Snip off the rubber bands and rinse thoroughly with water.Throw it in the dyer or hang it out to dry and your denim tie dye shirt is ready to wear!
