Hey Pumpkin Princess:
Hubby (DMTNT) already replied, but that was my little project last year, trying to recreate that POTC ride scene. I never got it quite right - I bought a cheap sheet from a goodwill store and trimmed the edges. My thought was to coat it with some sort of adhesive and get a thin layer of sand. I was trying to avoid providing the neighborhood cats with a kitty poop area, so I didn't want the sand too thick....We tried elmers glue - dried too hard, and cracked; then some type of rubber cement (can't member). Ended up throwing down some loose sand on top to fill in all the cracked areas. Once we added the finishing touches, it looked ok - pretty much everyone knew what I was recreating. But wasn't able to save the sheet. I'm thinking this year may need something sturdy (plywood?) under the sheet to prevent it from molding to the grass, causing the sand to shift...
I've been off the forum for several weeks (darn job!) - have missed this thread. Time to get fired back up again!!
