What I started with- 8x10 chalkboards (Amazon), and $12 frames from Target (glass and matts removed). The chalkboards were gray, and had an annoying border on them. So I painted them with more chalkboard paint, and popped the borders off (so they'd attach behind the frame without causing issues with hanging them). The borders were easy to pop off- probably not a pro most of the time, but for today it was great!
I also had to paint the frames gold. Like, HAD TO.
