When doing a foil project which does not have a zinc or lead came frame, do you use a wider foil so it has a wider solder line?
You do not need to use wider foil on the edges, but I have often done so to give the edge just as much "line value" as the internal beads. However this needs to be planned from the beginning. If you simply add a wider line on the outside, many times you will compromise the integrity of the design at the sides. You need to cut the glass a fraction larger to accommodate the thicker foil. Two millimeters added to the outside edge should be enough.
