Lay shirt on work surface and cover the upper portion with a sheet of plastic wrap. Fold the top portion down toward you and lay plastic wrap on the back of the shirt as well. Roll the upper portion of the shirt and encase it in more plastic wrap, closing the ends with masking tape.
Roll the bottom portion of the shirt up toward the top rolled portion. When they are touching, begin rubber banding, first at the two wider ends, then wrap rubber bands every couple of inches around both portions of the shirt. I wrapped my bands three times. Tighter wraps will results in more white in your stripes.
Turn on the faucet and run the bottom portion of the shirt under the water to dampen it. Squeeze out the excess water.
Cover your work surface with a plastic tablecloth and then with newspapers. Saturate the bottom portion of the shirt with red dye. Avoid the top portion, though as the shirt sits, there will be some seepage which is what creates the fun ombre effect!
Wrap the shirt in plastic wrap and allow to sit for six hours.
Remove the outer layer of plastic wrap. Rinse as much dye out as you can before removing rubber bands and remaining plastic wrap. Once you have removed those, rinse thoroughly then hand wash with a teaspoon of liquid laundry detergent. Rinse it well and wring out as much excess water as you can.
