I needed something quick and very cheap..the boxes are free...(I send a lot, so I order a lot) I had a styrofoam cooler that I cut up...lots of gorilla glue, then duck tape..my monster mud was way to thick so I used a putty knife like stucco (I like the way it cracked) painted it gray...dryer lint and green craft paint for moss and going to seal it with something like drylock to protect it for a year until I have time to make better ones!
Pieces of a plastic skeleton make a creepy entrance in this simple outdoor Halloween décor idea. Make the Halloween craft: Prop up an odd-shape piece of hardscape material at an angle. (In place of very heavy rock, use a piece of foam core, painted and streaked gray.) Tuck skeleton hands and skull, and feet if desired, in a pose and scatter fallen leaves.
