On NGS group we're doing a book study using Darlene Olivia McElroy & Sandra Duran Wilson's book "Surface Treatment workshop". We've looked at using stencils in a couple of the other book studies: Bernie's book and in Julia's book. But I was inspired with the information on using stencils as a surface treatment in Darlene & Sandra's book!!! I just played with 4 of their suggestions. (There is so much more info in the two pages of this section, I highly recommend this book.)
A reminder, you can find many types of stencils on the market, metal, plastic, paper and you can make your own using die cuts or cutting your own.
Redux: Stencil on top of book pages or old art. I decided it would be fun to transform the paper I use under my creations (worksheet).
Perfect Distress background I'd make earlier. I decided to use a black embossing paste (this not only added a color contrast, but a texture contrast as well), over a plastic clock stencil.
