So, I've been collecting insulators for over a year and a half. Finally built some shelves to get them displayed and off of my pool table. I was able to string LED rope lights behind them. I think it turned out pretty good. When I put them on the shelves, I determined that i'm already out of room. I have ~190 (mostly unique) and I don't think I can squeeze very many more onto these shelves. Good news is that there is room for two more shelves (below), so it looks like I'll be adding them in the near future.
