I gleaned this idea from a card displayed in the Craft Barn shop during their fabulous Extravaganza weekend.
The wall is stencilled directly onto the card. I found the best way to apply the ink is using a foam finger dabber because it effectively gives the appearance of the stone work texture. The cats were stamped onto plain card and then cut out.
