I depend on 5/32 BLACK BACK foil for my designs. I found out that the maker, EDCO, has discontinued the 5/32 size in BLACK. This has me quite upset, and baffled because they still make COPPER BACK in 5/32.. I don't understand because you can patina any color or leave silver with BLACK BACK. It is not noticible since inside the solder line is essentially a "black hole". With the COPPER BACK, you can only patina copper. Does anyoned have any feedback?? I worked so hard creating my designs. Honestly, this stinks. !!!!!!
