Design your own custom multi-opening mat collage board
Create your very own custom multi-opening mat. When you are finished designing you mat below, hit 'Add to cart' to save your item and add it to your shopping cart. Double-check your openings, measurements and sizes before completing your purchase.
It is HIGHLY recommended that if you wish to add a second mat layer, you add the second mat layer FIRST before making other design changes to your multi-opening mat. Adding a second mat layer, or changing the thickness of your second mat layer, will alter the size and position of your existing mat openings.
For the best experience, please use a desktop browser with the multi-opening mat designer.
Your overall mat size: " x " (width x height).
Generate a multi-opening collage mat
Turn the switch to 'on' to enable the auto-layout designer controls. The auto-layout controls allow you to automatically and instantly generate a uniform mat board.
*WARNING generating a new multi-opening collage mat will override any existing changes or designs you have made to your mat. After generating your design, you may still individually edit mat openings by clicking on the opening you wish to edit.
Edit mat opening #1
*All units are inches.
*If you have a second mat layer enabled, the left, right, top and bottom numbers below will reflect the distance from the outside of BOTH mat layer openings to the edge.
