When the water is near boiling, pour it into a separate container. Put on rubber gloves, shake the dye, and add it to the water. I’m using tangerine Rit dye. The amount depends on the color you want to achieve, and the amount of water you’re using. Stir and pour it over the fabric. The more you move around the fabric, the less mottled it will be. Let it sit for about half an hour, moving it around occasionally if you want a more even color. Using a larger container and more water will allow more of the fabric to absorb dye. I’m using a small container with tightly packed fabric, so the results will be more dramatic with areas of strong color and no color. If you want to use more than one color, pour different colors over areas of the fabric. The water doesn’t need to cover the fabric completely, so the colors don’t mix too much.
