Pin Reaper: Francoise
What I Did: I used Sally Hansen White On for a base and four colors of Revlon. The first press of the sponge barely transferred any nail polish. The second press removed what little had gone on the first time! I tried adding lots more nail polish including dabbing some directly on the nail, but by that point the new nail polish had softened the white base coat and you can see the result when I pressed with the sponge to blend.
Next Time I Will: My friend had more luck with only three colors and her polish brands were definitely thicker. I may try again with an eye-shadow applicator to sponge the polish on.
