I've also made a tie dye look using the wax paper resist technique and then sponging on the ink in a kind of round pattern. Here's the link for the technique:

To make it look like tie dye, instead of randomly crinkling the wax paper, fold it in quarters and then in half again and in half again so you get a wedge shape. Then crinkle it so when you open it it looks a bit like a spider web. That is what makes the pattern that the rubber bands make in tie dye.
