The Ships, Eugene?
Oh ,You mean all those models that come to a point at one end!
Well, let's see. You know those plastic cabinets they try to make look like furniture(Poorly I might Add). Well, one shelf area is devoted to keeping them( Card) out of harms way. The other shelf is for F.S.M. issues. All mixed up, but there! The Rest(Unassembled) are in a file cabinet sorted by Type and Printer.
The Rest. Oh, you mean the done or almost done ones. Right now on top of all the cabinets in my Bedroom. After painting two more walls, A shelf goes around the room 24 inches from the ceiling-Ships only! Planes, Five of them, will grace the corners of the ceiling away from that darned Fan!
I would put them lower, but out of harms way is best. My plastic models are in a Doctor's/Lawyers Bookcase( you know, the ones with Lift and Slide Glass front doors!) This way each has it's own display area. One shelf there is dedicated to Plastic, mainly in the form of those pointy things again!
