extremely valuable input for consideration.

So a hanging tapestry becomes much more viable, or if soome baffled foam 
were acquired it could be decorated before being mounted.

This whole thing sounds like it will turn into an ongoing process.

Waste styrofoam from packing could be mongoed at a best buy magic place of 
stuff or something, painted, cut up and mounted.

I guess my next question is does anyone have knowledge on sprayguns and 
have an air compressor for painting foam?
