About Multiple Window Collage Matting

Besides our large select of standard photo mat board sizes with single openings, Redimat is pleased to offer our selection of photo mats with multiple window openings in our most popular Economy White Core in Smooth White surface papers which is a buffered acid-free material that provides the aesthetic and design benefits of a bright, stay-white core. While all of the mat designs on this page are for the Smooth White color, if you would like any of them cut from one of the many other White Core colors we carry all you have to do is let us know by email or phone. The pricing is the same as long as all of your selected mat design is of the same color.

The selection of specialty and custom mat boards found here covers some of the most popular designs including "K2 School Years", "Name Plates", panoramic collages for a theme of images, collectible trading cards and are a fabulous way to pull together groups of family or vacation photos. Most of these mat layouts work well as both portrait and landscaped orientation.

Picture mat board with more than one window is sometimes referred to as collage photo mats and all of these designs may be cut from any of the matting materials and colors we carry from economy grade up to the finest museum 8ply cotton rag boards. If you have your own layout we can custom cut that for a virtually unlimited number of custom options with multiple window openings.

To complete your mat board project we also carry a wide select of backing or mounting boards that can be added to your order. For options please see the main menu under Mounting and Backing. If you need Clear Bags for protecting and selling your matted prints please see Clear Bags from the menu.

Purchase the pre-cut, multiple opening picture mats you are looking for at Redimat. Please contact us for custom pricing or more information to order these in other colors and mat board materials.
