Choose Your Fabric
Rit works best on many natural, washable fabrics such as ... * 100% cotton, linen, silk, wool, ramie

Never pour liquid or powder dye directly on fabric. 6. For the deepest color, use a water temperature of 140ºF/60ºC. 7. When dyeing 1 pound of dry fabric of dark or bright colors such as Black, Dark Brown, Cocoa Brown, Navy, Purple, Wine, and Dark Green, use double the amount, or 2 packages of Rit powder or 1 bottle of Rit liquid, in 3...
