I asked KP this about their blocking wire set, but they sort of gave me a vague answer (first time for everything!) This is probably a silly question, but since I’ve never used blocking wires, I don’t get it. If you have a piece that’s, say, 72" in length and the blocking wires are 32-1/2 inches long, do you just overlap and use multiple wires? The KP instructions say to leave out several inches of the wires at each edge for pinning, so would it be like 3 inches of wire edge, 26 inches of wire through edge of fabric, 3 inches of wire edge, 3 inches of new wire edge overlapping last 3 inches of wire edge, 26 inches of wire through edge of fabric, etc. or is there another method for wire blocking long items or are pins better?
