I have been using the same mylar supply for the past 12 years. I am starting to run out. Have been looking for more. All I seem to run across is what appears to be somehow different. Both measure out .010, however, the old stuff that I have always used is more opaque (top in the picture). Everything I find now, is more translucent. Im not nearly as pleased with the newer supply even though it measures out the same. I dont know what it is, could just be mind over matter. But Im looking for suggestions and am really hoping someone can point me to a supplier of the stock Im running out of thanks.
