Making a Mickey Mouse tie-dye shirt is as easy as can be. First trace a Mickey mouse outline onto a plain white shirt with a pencil. Using plain dental floss and a needle, sew around the tracing you've just created. For optimal results soak the shirt in soda ash (this step is optional). On the final stitch, pull on the dental floss until Mickey's head "pops up". You will need several rubber bands for the next few steps. First tightly wrap some rubber bands around Mickey's head. Add additional rubber bands spaced evenly 2-3 inches away from each other over the entire shirt. Now put on your gloves and take any necessary measures to avoid staining furniture by placing newspapers or plastic on the area you will be working. Begin the dying process by selecting a color and dyeing the Mickey head, then cover the Mickey head with plastic wrap to avoid the colors from mixing. Then dye the rest of the shirt using alternate colors. Finally wrap the entire shirt in plastic wrap and let set over night. Unwrap in the morning to find a beautifully Mickey Mouse shaped tye-dye shirt!
