After I painted the background, I used the harlequin stencil with the masking fluid. After the fluid dried, I applied layers of water colors and then pink color spray and blue color spray with more stencils.
When everything was all dry, I rubbed off the masking fluid to reveal the first layer of color underneath.....which is the yellow and light pink areas.
I'm so glad that I decided to experiment, because I had no idea if this would work! I really love the effect and can't wait to try it again!
Take care and God Bless!
