Learn to make foam-slab tombstones with witty epitaphs to decorate your yard for Halloween.
For an aged copper finish, mix one part each of White, Candy-Bar Brown, and Avalon Blue. Dry-brush and/or sponge the mixture onto the tombstone, concentrating on the bottom portion but not covering the entire stone. Spray on a light coat of Forest Green paint.
For a gray stone look, pour White and Black crafts paint onto a disposable plate. Dip the sponge onto both colors and, using a dabbing motion, apply on tombstone. Add Black to the sponge to make the edges darker. Rinse the sponge, and then add some White using gentle, tapping motions. Allow to dry.
