I am not sure where this idea came from but it came with a sort of urgency, I had done lots of line drawings in bar years ago but rarely a 3-d version . The idea of the left over nots just jumbled in the bottom appealed too and the whole thing came together fairly rapidly.I wanted to get many of the details right and originally I was going to do a grand piano but this one seemed reasonably achievable and it needed to be white to stand out on the grass. Whimsy I guess but quite satisfying.
