I used the Cricut Cartridge Fancy Frames. I tried to make a 4x6 opening but didn't quite make it. Going to play with it again and see what I need to set the Cricut at to make it a 4x6. I used the Union Square Recollections paper pack, the Love paper. Its all the way on the right side, so I cut the paper, then used a piece of the red paper as a mat and then added the Fancy Frame mat.
