I was bored last night, so I got around to hanging the gallery wall over my bed. I did miscalculate how much vertical space I had to work with, so the last two pieces wound up shuffled a bit.

I used a laser level, painters tape, and chalk to maintain lines and spacing.

Most of these are from Society6, but a few are from Redbubble and AllModern. [Sources]

I still need to hire someone to help me with the weird sandpaper texture on the walls and the popcorn ceilings. The previous owners used some kind of paint/mud/sand-texture stuff to cover old wallpaper. I can barely make a dent in it. A large strip of old wallpaper border came down when I hung my curtains.
