The process is amazingly simple. Soak your slipcover in the bathtub, start your washer and follow the directions on the bottle. I used a mixture of purple and fuchsia to come up with this eggplant color. It was absolute perfection. I adored my purple couches, and if you take a look at the RIT website, the options really are endless! They have a gorgeous honeysuckle rose, the perfect shade of aqua, and so much more. When it was time to move out of my apartment and into a home with my husband, I gifted both couches to a friend of mine. Her decor didn't include purple, however, so she bought two natural slipcovers and did a little dyeing of her own. As far as the dye, for the purple I used 5 boxes each. When I helped my friend dye them red, we just used one bottle per slipcover. It also calls for a good bit of salt, but one big container will be fine. I honestly don't know how much water you'd need if you're using a bathtub/container method. Hope that helps!
