On my last birthday my friend brang me rare tennis balls with soviet star and name Leningrad. They were pretty nice. But they were not suitable for play anymore. Time made them too rigid. But they were too cool to throw them out. So I decided to use them as a material in my new pinboard! It consists of plywood base in form of table lamp and part is filled with tennis balls. And I can save and keep notes and drawings just pinning them to plywood panel or balls.
So here it is my new lampform pinboard in eight steps manual if someone will want to do something similar.
