To make a spiral tie dye t-shirt, you first make different colored dyes by boiling water and adding dye to separate bowls. Then, you spray water on a cotton t-shirt, twist it into a spiral shape, and secure it with rubber bands. Next, you dip different sides of the twisted shirt into different dye colors and let it dry with the rubber bands still on. Finally, you remove the rubber bands, unfold the dried shirt, and have a finished spiral tie dye design.
