It's an 8' wall and I found chicken wire used for corners on stucco prep and they are 8' long. (I think I paid about $3). I nailed it into the wall and as you can see, it supports quite a few pieces. The cat on the top left side is in a frame because I wanted to see how it looked cropped. I won't keep it up there like that, but as you can see the wire is study enough to hold it up. I thought about six penny nails or "L" brackets to further support it, but I'll wait and see how it works first. I'm using clips and picture frame hooks. I'm really happy with it so far.
