We all knew it would come to this. More space was wanted, so the closet doors came off.
I say that like it was easy, but it was a bit of a challenge for Roomy, who was inside the closet in the relative dark, trying to unscrew the runners and lift the doors off. The runners proved to be stubborn, but Roomy proved to be more stubborn, and in the end the doors came off.
We began re-arranging things. Much of what was stored in the closet (backcards and packaging mainly) was shifted under Roomy's large display table. Then smaller bookcases were shifted into the closet so that it could become an extended display space for me. Along with my small LPS collection, I've moved some of the G4 ponies in there. The G4s will have two small displays (Ponyville and Canterlot) and the G3s will gain some shelf space in this way, as well.
The Cave will always be a work in progress, so long as our collections continue to grow. We may look at ways of adding shelving in the closet at a later date. In the meantime, we've got a bit more room to move now.
