I love how these decals are really opaque. They show up very well on the base colors I used.
You can get these decals here:
Anyways, I first painted 2 even coats of yellow and blue.
The colors I used are Onl DD #11 (blue) and #34 (yellow).
While waiting for my base colors to dry, I cut out the images I want and removed the top clear film.
I soaked the decal in a bowl of water for about 10 seconds.
Using a pair of tweezers, I peeled the decal off from the backing paper. Then I just put the decal on the nail I want. Used a tissue to dab off excess water. Lastly, apply your favorite top coat to seal in the design.
