Today's tip is designed to help you mat your photos or cards quickly and precisely because matting matters.
Place your photo or image to mat on the corner of the paper. Space the edges evenly on both sides using the width you would like for your border. Use removable adhesive to tack it down because at that point two of your edges will already be measured & "cut". Lightly mark with a pencil your measure for the two remaining sides then trim & you are done.
If you want to save money when matting, you can cut out the centers of your mats, leaving the border behind your photo intact. Use the scraps left over for smaller accents, mats or letters. When you create a frame by putting your mat behind the picture, the paper directly behind the photo doesn't show anyway; so cutting the centers of your mats will save you paper.
I hope you found this tip helpful.
