I have several stencils with small patterns. Not sure where I got them, but they were for doing other then cards.
There are stencils ,in almost all departments , of the craft stores. I think I counted five places we found stencils in JoanAnns store, and all different prices. And different size patterns are for different projects. If you are putting a pattern on a glass, or a wall you need different size holes of the pattern.
So look at different hobbie departments
