Here's a better shot of the wall. I used carpet tack strip at the top & bottom to secure the felt.
And here with a couple projects already needing to be finished but it's too grand to be able to see them on the wall!
I'm not crazy about the felt. The smaller one I made was with a flannel backed tablecloth. Fabric really sticks to that a lot better than this.
The beauty of the tack strip is that it holds the material evenly top to bottom but if I want to change I simply lift it off. I put an extra piece of felt on the bottom to completely cover the tack strip so I don't catch it on anything.
Still cleaning the rest of the room.
