|In this photo you can see the small pieces of gatorboard that I cut with the knife, but you can use fomecore, too. I'm using foam tape, but any double sided tape will work or glue. And you can see the cutout of Buffalo Bill I found behind a filing cabinet that I'll use for the picture.
||I've put a small piece of tape on each square of gator and I've taped them together in a stack like pancakes.
||Here are the stacks taped to the back of the photo. I used two pieces of gator taped together on the top and the bottom of the cutout. You can see the tape that will be used to hang the photo to the panel. You know, a piece of velcro with the sticky back on it would also work well. Then stick the other half of the velcro to your panel and you can take it down when you're moving it and put it up for display!
