Soak fabric in a large pot of hot water and dye, and stir regularly for 30 minutes. Once the fabric has been dyed, rinse, wash and dry it. The entire dyeing process takes about an hour and a half.
- Gather your supplies
RIT dye is easy to use and commonly available at craft, fabric and even grocery stores. In addition to the fabric and dye, you need a 2-gallon stainless steel pot, a large spoon for stirring, salt or white vinegar, and rubber gloves. RIT dye works best with fibers made from natural fibers. If you are trying to dye 100-percent polyester or acetate, consider other specialty dyes from a fabric store.
- Heat the water
Fill the large pot about 3/4 full with water. Bring it to a boil, and then reduce to a simmer. If dyeing nylon, add one cup of vinegar. For silk, add one cup of salt.
- Add the dye
Add the entire bottle of dye to the water. If you want to create a custom color, check out RIT's website for a color chart with recipes.
- Soak the fabric
Submerge the fabric in the hot water bath, and stir often for 30 minutes.
- Rinse the fabric
In a stainless steel or utility sink, rinse the fabric in hot water until it runs clear. Machine wash or rinse the fabric in cold water, and machine dry on hot if possible. The cold water and hot air help to set the dye.
