Homemade alcohol ink. 2 methods. One: in a baby food jar, pour 1 pkg powdered Rit dye, fill with rubbing alcohol and shake until no grains remain. Method #2: (this won't be grainy) mix ½ cup of isopropyl alcohol (NOT rubbing alcohol) to every two teaspoons of liquid Rit dye. You may want to add more dye as necessary to create a deeper color, but a little goes a long way.
