Soaking a shirt in vinegar after dyeing is not strictly necessary, but it can help set the dye and prevent fading. The acetic acid in vinegar can help fix the color, especially for natural fibers. If you choose to do this, mix one part vinegar with four parts water and soak the shirt for about 30 minutes before rinsing.
No you dont have to, but when you do soak it in soda ash before dying the shirt it will completely hold all the color in. When you dont only a small portion of the color stays in the shirt fibers.
You can substitute soda ash with baking soda mixed with warm water to pre-soak the shirt before tie-dying. The ratio is 1 cup of baking soda to 1 gallon of water.
You use cold water to do this. First, soak the shirt in white vinegar to set the dye so it doesn't bleed.
