I just got the photos back from the store and they look great, I found out that there're not a hundred percent square but they look square enough. I've also decided to use blu tack to stick it to my wall so I can reuse the pictures if I stop get tired of it. Also so I can swap out the photos if I want to. I'm not actually sure if it is going to stick well but I'm just going to hope for the best.
I think I'll be doing the wall later today or tomorrow. I want to get it done before I leave so I'm trying to work it into my schedule,but I'll really hoping it will work so wish me luck and have a great day.
