I bought and installed gallery rails in the living room. We wanted to completely re-arrange alle the framed stuff there, and I didn’t want to turn the wall into swiss cheese. The hooks I’ve bought have been a bit beefy for some things I needed to hang, so I had to put a few of them to the grinder, but all in all this made the walls very neat, and easily to rearrange later.
