I decided to make my own trendy marble-effect dyed jeans and it turned out to be easy and fun. Here's what I used:
2 Boxes of Rit Pearl Grey Dye
Prewashed White Cotton Jeans
4Cup Measuring Cup
2 Gallon Plastic Container
4 Large Rubber Bands
Plastic Table Cover
1--Scrunch up your pre-washed jeans, starting from the bottom of the leg all the way to the waist.
2--Wrap each leg with rubber bands.
3--Then wrap legs and top of jeans together. Note: A tighter binding will produce more white areas.
4--Soak the jeans in warm water for a few minutes. Now, cover your work surface with plastic and grab those rubber gloves.
5-- Mix 2 boxes of Pearl Grey dye with 1 cup of salt in 4 cups of very hot 140˚ water. If your tap water's not hot enough, just heat some in the microwave or tea kettle.
6-- You can test your dye color by dipping a fabric scrap in the dye bath. If the color is too dark, add more water to adjust. If it's too light, just add some more dye powder.
7-- Add 1 gallon of very hot water and stir well. Immerse your wrapped, wet jeans and let set for 20 minutes. To help the dye penetrate, occasionally turn and push down with a big spoon.
8-- Lift from the dye bath and remove the rubber bands. Rinse in cool water until water runs clear. Wash in warm water with mild detergent, rinse and hang dry.
