It's fairly simple. Begin with a base colour, wait for it to dry, place the stencil on the nail, paint with another polish, then before it dries, remove the stencil. The stencil removal step needs to be done quickly.
I think my nails would have looked better without the flakies over the silver, just the purple. I think it would have given it a crisp look by showing the design lines off better.
What do you think? Are stencils something you would consider using on your nails?
