After practicing a lot, I finally have a nail stamping win!
And with flash:
Much better than the previous attempts!
Base color: Revlon Raven Red
Stamping color: Revlon Coastal Surf
Stamping plate: Gals GA21
I initially wanted to have a lighter shade of blue, but the ones I own are too thin for transferring. Coastal surf is a great stamping color, so I tried it and I think it looks pretty good!
