Tox, for Rit powder dye I use about 6oz of alcohol to a package of dye. On the liquid stuff I use about the same 6oz of alcohol bt I mix in the dye until I get the color I want. Remember to shake the liquid dye before mixing it into the alcohol.

Watch out for the colors on the powdered dye. I think some of the dye pigment does not dissolve in alcohol. Rit powdered black give me a beautiful plum color. It looks really good but it's disappointing if you're looking for true black.
