Press the shield to the copperclad, drag a marking pen over the appropriate opening in the shield, and you *might* have straighter and better-looking traces. As for the Opaline bag, I think there's one in my supplies cabinet, along with a motor-driven eraser that can chew its way through a sheet of paper in no time at all if carelessly used<g>. 73-- Brad AA1IP
