Alright, longer one, so here we go.
Years ago, I even had a thread here about it: I standardized the shelving in my room. Well, I had to change the layout of my room since I put the shelves up: internet reasons mostly. But I didn't change the shelves. The important bit was: I put up two flat shelves over my bed in a L shape. Recently, I took half the L off the wall because the shelf was just empty, and I kept hitting it when I changed the bed linens.
But the wall was missing texture, so I found some of those squares to put up. Much lower profile, and on massive sale, 5 bucks a box. But walmart would only let me buy four of them.
20 bucks ain't much... so... done. I can figure out other places to use the rest. Maybe pawn a box or two off on my brother for a profit.
Well, took two hours, but... at least there's nothing to pawn off elsewhere. Not happy with the pictures on the top left... probably going to move them again... but otherwise quite happy with how it turned out. There's nice texture on the wall, it'll pop more once the room is painted (lighter colour.) and a lot of little odds and bods can be move into it, and there's still more space for blokees.
