I used to do hope chests that I'd carve celtic knotwork into and give them as wedding gifts. I bought the wooden chests and then dremel carved the designs and although they were a ton of work I was pretty happy with how they turned out. Then I got some bad reactions, a few friends got divorced so then I started to feel like they were bad luck or something equally dumb. I want to start back up again because I still need to make 2 more for brothers.
But here is what I used to do....
This is an internal music box movement. I can't remember what it plays.
I needed a pencil box for an art class and the only way I'd keep it and not give it away is if I put something weird on it. It's worked so far.
