I bought these ClosestMaid ShelfTrack 40″ wire shelving brackets (2) and anchored them into the studs on the wall (each was about $9). I wanted to be able to adjust the support brackets at any height. The support brackets came 2 in a pack and were about $7.
Sometimes I use fabric for backdrops and they’re not always the same length. I also bought 1 1/2″ PVC pipe and used packing tape to attach this Valentine backdrop. I can store them like this or stand them up in the corner. I love having options, lol. I purchased all these products at Home Depot (except the backdrop).
