In other progress -- we bought die-cut velcro circles from nametags4u.com, and Andy sewed the hooks to our patches and the loops to the sleeves of our new BDUs.
We've bought a 15' shock-cord-strun tent pole to bend into a semicircle to tension a center curtain made out of white ripstop for the rear-projection of the Abyss effect. It'll be split down the center so we can actually walk through our "event horizon".
