I've expressed my love for dry water marble before. I had a few dry sheets around that were made about two weeks ago. The polishes were a mix of sally hansen and china glaze.
I wanted to try some nail art with them so I cut the sheet into thin strips.
The base is sally hansen green with envy and going green. About 2/3rds of the nail was painted with green with envy. I let it dry for about 5 minutes. Long enough that my finger wouldn't leave prints on the nail polish when I touched it.
I then took the strips and placed them on my nails (polish side down). I pressed down on the strip and peeled the plastic right off. It was complete with a coat of seche.
