Big garbage can or bags for trash We have chosen vibrant popular primary colors that cannot easily be mixed themselves, but with which you can mix an endless variety of colors. If you have other color needs, buy this kit instead, with no colors, then choose from our preselected color combinations here, or choose your own individual colors here, or use them to supplement this kit.Important note: *dye colors with *, need to double amount of dye to get dark color, dye with **, need to quadruple the amount of dye to get dark black. So these colors don't go as far as the other colors. If you want to have more of these colors, let's say you have some Goth kids who want to do lots of black, you can add some 2 oz jars to supplement your kit. But the 6 - 2 oz jars of dye, even with this constraint, do make enough total dye liquid to dye 100 shirts averaging size Adult L, depending on how heavily your participants squirt it on. You should be able to dye even more if you are doing mostly kids shirts, and less if you are doing lots of bigger shirts or things like dresses. The kit comes with enough chemicals so that if you do add some extra dye, you should not need any more chemicals.See the Instructions tab above for some handy group instructions. The book that comes with this kit also has group instructions and helpful hints in the back, as well as well illustrated ways to do easy patterns.
