Cut Foam

Cut foam along sketched outline with a serrated bread knife. Since this step is messy, it's best to do it outside. Keep blade perpendicular to foam and use caution while cutting.

Draw Design

Sketch out tombstone design. This can be a funny saying, a cross, RIP or anything you'd like. Keep designs simple and easy to carve. Tip: The tombstones will be painted, so sketching mistakes will not be visible.

Spray-Paint Tombstones

Paint all tombstone surfaces with a can of black spray paint. Work in a well-ventilated area and apply paint in long even strokes. Spray tombstones from multiple angles to ensure good coverage. Allow ample dry time.

Dry-Brush With Acrylic Paint

Apply a thin coat of dark gray acrylic paint with a 2 1/2-inch sash brush. Drag brush along tombstone surface, preventing paint from getting inside carved design (this method is called dry-brushing, as very little paint is used). Allow this coat to dry.

Apply second coat in the same manner, but in a mix of dark gray and white acrylic paint. Allow second coat to dry.

Apply third coat in white acrylic paint in same manner as the others. Adding multiple layers of paint will give foam the appearance of granite. Allow final coat to dry. Tip: To place outside, insert bamboo skewers into tombstone and stick into ground.
