A few months back, a friend of mine passed a couple of side tables to me, and I took them not yet having a plan for what purpose they'd serve. But I knew I'd give them some form of paint treatment and I'm happy to report they are now functioning in my home.
While I was at it, I also painted an old canvas I've had for years that just wasn't my taste anymore and the backing of a frame -- also gifted from a friend.
An old table, canvas or picture frame.
Chalkboard paint. (I used spray-on and brush-on)
