10. The Slanted Broken Grave Marker
Asymmetry enhances a spooky atmosphere. Construct a headstone that appears broken in half diagonally, with the top piece glued at an offset angle resting against the base. Paint exposed jagged edges with earthy tones and dark shadows. When staking this prop into the ground, tilt it at a 15-degree angle to make it look sunken into decades of settling soil.
