Hi lesavoir, thanks for the reply! I contacted a number of local arts supply stores, however none carry a large enough sheet in stock. I would need a sheet approximately 50" by 30" to cover the screen. I ended up purchasing two oversize 42" x 30" sheets. The sheets work fantastically

, but there is a very clear seam mark down the right side of the tv since I had to use two sheets

. 30" x 20 yd rolls of drafting mylar seem to be available from ~U.S.$100, but that is 14 times as much film as I need! Do you have any recommendations? Thanks again!
