<DIV>I was at a garage sale earlier today and found a large piece of Gortex fabric that a woman had planned on using to make some rain gear for her kids, but never got around to it! It was only $5 and is enough to cover the back of 2 vertical pianos. I've been checking on the web and there are places you can buy Gortex for $17 a yard: <A href="http://www.rockywoods.com/breathables_main.htm" target=_blank>http://www.rockywoods.com/breathables_main.htm</A> </DIV> <DIV>There are other lightweight waterproof breathables that sell for less.   Wouldn't a lightweight waterproof breathable fabric make the best back cover? Or is this overkill? It seems like it would work better than the "grill cloth" that Dampp-chaser sells. </DIV> Ryan Sowers, RPT Puget Sound Chapter Pianova Piano Service Olympia, WA <hr size=1>Do you Yahoo!?
