Better than spray snow!
My mom used to use pink glass wax and stencils when I was a kid.  Can't find it anymore, but window wax is the next best thing.  Dampen sponge, use just a scant bit of the window wax, which comes out of the bottle a brownish color, and let it dry to a snowy white color.  It is less messy than spray snow and all you have to do after the holidays is wipe off with a soft cloth to leave your windows, microwave, or whatever sparkling clean and without streaks!  Do not put on wood!  Fun for kids to use with stencils.  Heck, fun for adults to use with stencils!!
