I have a friend who is a wedding coordinator, and she was doing a Gatsby themed wedding, which needed a marquee frame for a chalkboard picture she wanted to make. She couldn't find a nice (suitable) old frame to drill into, so she asked me to put something together for her.
The chalkboard comes out so she can put a 24" x 36" poster in there for an entirely different look. The whole thing is self-enclosed so that the wires aren't all sticking out the back.
I think it turned out pretty great - what about you?
There are more details about it on my blog.
