I like that the cases also have somewhere to live, but I like the idea that the guitars don't have to live in their cases. It's more incentive to play if you can open the cupboard and pick it up and play without having to open the case.
CD cases or shelves out of pallet wood. While this is a good idea as it is I started to think about it. Wouldn't it be a good idea to do variouse sizes to fit DVD's. old cassettes, videos (yes we still have a load of those). I think that would make a very interesting visual display simalar to these or screw them together as a single unit ;)
