Edco13/64 Black Backed Copper Foil

I swear by Edco black back copper foil tape for my stained glass projects. I ran out of 7/32 and out of ignorance and desperation had to get a different brand (studio pro). The other pulled away from the glass and I had to redo 2 projects! I will never NEVER use another brand of copper foil again. Best brand ever on the market and the sizes available are perfect for Tiffany Style projects
