This technique could NOT be any easier. All you need to do is take a variety of Color Wash Spray colors and spray them liberally onto glossy or matte cardstock. Voila! A gorgeous background piece to work with!
A simple homemade recipe for Color Wash:
Squeeze approximately 30 drops of Stazon Reinker into a small spray bottle. (You can use regular dye ink as an alternative. Stazon inks result in very vibrant colors!)
Slowly add 91% rubbing alcohol to the ink.
Keep testing the color intensity with a small test spray on a scrap of glossy paper
Stop adding the rubbing alcohol when you are satisfied with the color!
Mix your colors to come up with unique blends!
