how to make a mat for a picture frame collage
Steps: 1  1. Select a paned window with panes that are roughly the same dimensions as your photos. 2  3. Cut mat board to frame each photo and then tape the photos to the back of the mat board. 3  4. Cut out 1/4-inch thick backing boards to hold photos in place of each frame.
The basis for the collage was to create a mat to fit standard 8 x 10 or 16 x 20 frame sizes to print on a home printer or to order a print from an outside source. After making the Triptych action, I decided to not create anymore new actions but just provide PSD templates, since the Elements users could not run the PS actions.
