Mix 1/2 teaspoon acid dye with a small amount of very hot water, stir, then add 2 tablespoons white vinegar (not malt). Top up the cup with more water. Dilute for paler shades. Lay out a piece of plastic wrap on your plastic. One piece is enough for a skein of this size. Start apllying dye. You can apply the colours randomly, or in order. Here's the skein with 2 greens, turquoise and gold. Later skeins are painted differently. Turn the skein over as well to make sure the dye penetrates underneath. When completed, roll up the plastic wrap from side to side, and then end to end. don't strangle your skein though! It doesn't have to be airtight.
