OK, here’s another problem inspired by matting pictures. Suppose you have an image that you want to put in a standard 16″ by 20″ mat. You can print the image any size, but want to keep the original 2:3 aspect ratio (meaning that the length will always be 50% longer than the width so you won’t […]

I have a faster and more accurate way to make sure my Logan Model 660 Framers Edge mat cutter is square that does not use a carpenter’s square.
