Hey there! I’m kinda stuck on how I should do the placemat on this wall with photo ledges. I really want to do a photo wall with all of our favorite bands. I’ve looked on Pinterest and can’t find anything I seem like, placement wise. I don’t want to do one long ledge. I would definitely prefer to do at least 2 or 3 shelf ledges. Any ideas on how you would place shelves? Thanks!!

First pic is wall in question. Second pic is couch dimensions. Third picture is example of ledges.
