The collage is straight forward to make and requires no special tools. You can customize the paper and frame with embellishments if you would like. I thought about staining and stitching the edges of my paper, but decided to keep the look simple and clean, which suits me just fine.
Starting with 9 frames (8" x 10"), I cut coordinating card stock paper to fit each frame. I then centered and adhered each photo to the card stock paper using an acid free adhesive. Once assembled in the frame, I hung the collage on the wall in a grouping. Random placement would be cute as well.
Really, that is it! Give it a try. It is an easy, inexpensive and fun way to cover wall space.
