Hello, Roy and the group--

Nothing, really-- In response to Bob Roomberg's experiments with marker pens
as dispensers of resist for PC-board paths, an erasing shield might
serve as a
"mask" or template for creation of uniform traces on handmade boards.
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>.
