I need some visual aid to help measure mat openings. Many antique prints have graphics and/or text that do not line up vertically/horizontally, and I have a time getting the height/width perfect. Perhaps someone has seen such an animal in a design graphics setting. I would be able to lay the sheet over a print and line it up exactly. All leads are greatly appreciated!
