Stencils on Buttons

I gathered these stencils are for etching on glass. They were very intricate and a filmy material that clings to a surface. I used the 1" wide border strip at least thirty times before I was done with cabinet (see below) and it was pretty much done also. But I wanted to see what would happen on a button. I used one wing of the larger butterfly on a 1 1/4" MOP button and one wing of a tiny butterfly from the strip on a 3/4" button... They are VERY rough but I can see that stenciling on buttons has lots of possiblilites and I am going to order another packages. I purchased these at

but I'm sure larger craft stores would carry them....
