drywall

I have started a new tombstone, I'm going for a realistic stone that you might find in a real graveyard First I measured and marked my blank, it's 24"x24"x3/4" ridged pink foam from Home Depot Next I cut out two for the front and back I took the scraps and made sides and top and sanded it...

SO. I think I messed up the mixing ratios, or maybe the materials themselves. Not sure. Lowe's didn't have a 'box' of drywall compound, just an 18 pound sack. Mixed that with the latex paint and water...was pretty sure it was a total failure but 45 minutes later, the fabric was sure enough...

A few years ago I hung a pirate fabric all over my ceiling and black sheets to cover my walls. I used 3M removable hooks to hang everything. When my husband and I removed the 3M "removable hooks" part of our drywall came off with it. We tried everything to not get the ceiling/wall to come off...
