We cut up several garbage bags to use as mini-tarps, sprayed down with pam to make it easier to come off the plastic.
Some of our attempts:
And we went a little starfish crazy...
Also did two large and long seaweed-esque/kelp backdrops. Which turned out much more awesome than I thought they would.
It was after this was completed that we realized how freaking hot it was and scurried back inside to cool down. We actually got a lot more done than I had anticipated. We went through all 6 cans of foam, and I think took care of a large bulk of the foam. Might need a few more cans for either touch up, or a few more pieces, but it stretched pretty far, considering. All in all, we ended up a bit tired, but not totally exhausted, and neither of us got heat stroke. I'm counting that as a win!
