One other question:  if one is going to hinge mount and NOT USE GLAZING, is
a window mat overlap of 1/4 inch enough or is more recommended eg 1/2 inch?
I would be using 8 ply mat board and endeavouring to follow the instructions
in the previously posted tutorials re hinging the mat window to the mount
board and then hinging the image to the mount board.
