  1. Cover work area with plastic table cover and have paper towels handy to protect against any possible spills. Gather supplies.
  2. For best results, prewash swimsuit to remove any finishes that may interfere with dye absorption. Leave damp.
  3. Wearing rubber gloves, fill a stainless steel pot with 3 gallons of water. Add 1 teaspoon of dish detergent to help promote level dyeing. Cover pot and heat water on stove top to just below boiling (200 F° or greater).
  4. When water begins to simmer, add 1/2 bottle of well-shaken dye and mix well. Keep temperature at a low simmer for the duration of your dyeing.
  5. For solid overdye, simply add the swimsuit to the dyebath and stir slowly and continuously. The first 10 minutes are the most critical. Stirring helps to ensure an even color with no splotches.
  6. When desired color is achieved, remove from dyebath. Fabric will look darker when wet and will dry lighter. Squeeze out excess dye.
  7. For swirl tie-dye, lay swimsuit out flat. Pinch center and slowly twirl to create a flat circle.
  8. Secure with rubber bands.
  9. Dip half of bound swimsuit into the dyebath to create swirl pattern
  10. Repeat Step 3-4 to create another dyebath in another color.
  11. Dip the other half of the bound swimsuit into the dyebath.
  12. Wash in warm water with a mild detergent, rinse and dry.
