If I ever have a lake in the garden of my dream house, this idea might be very suitable! I'd pick a different guitar design though. Brian May's guitar, Slash's, . And that hole in the middle of the guitar?
If you're anything like me and cringe every time you throw something in the garbage that's perfectly reusable but you're really not sure where to recycle it, the garden just might be the place. So many household items that we get tired of or that.
