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: 14" x 10" (width x height).

Add a new mat opening

Add a new mat opening by selecting the shape of your opening below. Once you add your opening, you can position it where ever you choose. Mat openings must be 1 and 3/8th of an inch from the edge of the mat, and 0.5 inches from other mat openings.

Control the mat designer grid options

The grid helps you design your mat and make sure everything is precisely sized, positioned and spaced. Turn the grid off for freely move and resize your mat openings. Turn the grid on and the mat openings will resize and move in increments of the scale you choose. For example, if you select 1/4 inch, your mat openings will move in increments of 1/4". The visible grid will always be 1" squares, even if the grid movements are 1/2, 1/4 or 1/8th inch.

Select the total size for your mat

Changing the size of your mat after adding openings may shift and reposition the all or some of the openings on your mat. After changing the value in the inputs, your mat will automatically change size, and you may close the window.
