Stencils are such a versatile tool to use on cards and scrapbook layouts as well.  Stencils can be used with inks and or embossing pastes.  There are many wonderful resources to purchase stencils or discover stencils that you have in a drawer.  I taught a class today at Scrapbook Cove using stencils both for inking, and embossing.  Take another look at what you already have and start creating!
