It's always hard to think of something to do that's crafty for a guy. . . but I was able to come up with a couple freezer paper stencil ideas for my father-in-law and my brother-in-law.
This one was for my father-in-law's 60th birthday . . . I drew an abacus and cut it with my cricut on freezer paper. The orange paint looks quite neon in the picture but I promise it wasn't that bright.
