Important Do's and Don'ts
Do use 1/8 inch as the smallest measuring unit. Plan your sizes accordingly. Avoid measuring in 1/16 inch units or smaller.
Don t use the picture border as the image size and expect the mat to fit precisely to the border -- it won t. You must plan to overlap or leave white space around the image.
