Print these business cards. Cover the presidents faces with clear packing tape. Then you paint over their faces a few coats of a simple mix of 1 part liquid soap to 2 parts silver paint. Let it dry and you have scratchers. The kids love this game. Super easy and very popular!
You may have seen these on pinterest. The lotto part was actually the most time consuming for me to create. The painting was the most fun.
I have also tried laminated the full sheet, painting all of the faces, then cutting. It worked pretty good. The cool part is if you mess up with the paint, it does just scratch off. Also, if your dish soap smells, your paint will smell good too.
