lolI don't have a dedicated "store room" as such, more of a collection of places that I hide stuff until I can find a use for it!
My attic is full of stuff, my shed is full of stuff, my office at work has loads of plastic stuff in it, sheets, containers, drums, piping etc ( I work in plastic recycling).
Come to think of it, I think I have a bit of a problem, lol.
