Making a crypt for halloween

To make this crypt you'll need two sheets of 1"styrofoam (2' x 8') and two tubes of styrofoam glue. I prefer the pink/blue styrofoam for this project because I can get better detail than with the white styrofoam. White styrofoam will work, but it's messy. Other tools you'll need: a measuring tape, marker, saw, a straight edge, a rasp, wire brush, acetone, and paint. If my cuts are a little off, I use some paintable, exterior caulking and everything blends in pretty good. It's supposed to look old and worn and imperfect anyways…...
