Place the fabric into a plastic bag, then tie the bag shut. Be sure to press out all the air inside the bag. You can also place the fabric into a large, re-sealable plastic baggie (i.e. Ziploc bag), and then zip the bag shut. During this time, the dye will set into the fabric. Try not to move the bag during this time, or you might mess up the colors. It would be best if you left the bag in a warm, sunny location. This way, the heat of the sun can set the dye into the fabric better. If you are having trouble getting them off, cut them off with a pair of scissors. Once again, food coloring can stain your hands, so you should do this with a pair of plastic gloves. If you need to set the fabric down on anything, cover the surface with plastic wrap, wax paper, or aluminum foil first so that you don't stain it. Mix together 1/2 cup (150 g) of salt and 1/2 cup (120 mL) of water. Dip the fabric into the salt-water, then pull it out and wring out the excess water. Hold the item under a faucet, then turn the faucet on. Let the water run until it turns clear. You can also dip the item into a bucket filled with water, but you will need to keep changing the water until the water stays clear after dipping the item into it. You can hang the fabric up to air dry, or you can toss it into the dryer to speed up the process. The heat from the dryer might even help set the dye into the fabric better.  Be aware that the colors will be faded once the shirt dries. This is the nature of using food coloring as a dye. Do not use a dryer if you used silk, wool, or nylon. Food coloring is more of a stain than a dye. It is not as permanent as actual clothing dye, and it will fade over time. It may also release color the first few times that you wash it. In order to prevent staining the rest of your laundry, you should wash the garment separately for the first 3 washes.
