Instead of writing a couple of addresses, just cut them out. This way you can just send a piece of wood and your buddy won't mind that it doesn't literally say anything. The material speaks for itself. Besides, sending an old-fashioned message is what email and IM and text message and cell phones are for.

Or burn it out. I grabbed the nearest stencil font I could and dumped in a couple of addresses in Illustrator. I then sent that over to a laser cutter and after a few tests with the material I cut out the whole thing. If you do this, it's important to reverse the stencil since the wood can get charred. I could've tried to clean it up a bit, but I like the burnt effect in there so I left it.
