Although not on the list, I just received an email from a theatrical co-worker.
They have come across what he says is "Several Dozen yards" of 'decent quality' forest green duvetine. Normally in the theater, this material is black that is used for masking, tears in straight lines for ease of 'cutting' and can block all but the brightest light. It would be excellent for masking anything in natural surrounding. I am going to be taking it off his hands for some costume work but do not need several dozen yards. Wanted to know if this is something that the chapter might like? I have limited space for storage these days.
