Add a bit of interest to your house plants with a mini Doc Brown Grave stone as see in Back to the Future Part 3
Cut out the Tombstone and using a fine sand pad sand the surface until all the shine has gone.
cover with black acrylic paint making sure you get into all the details.
rub off the paint allowing the recess areas to retain paint
dab grey and white paint over the surface add realistic depth.
Great Scot! you've done it!
