Well, it's not that easy to answer. Yes and no. I usually organize my stash just prior to shop hops. I know I'm going to buy more, so I organize in advance. That way if DH is watching me "fit" my recent (un-needed) purchases, they go in relatively easily!
Actually DH is looking to move and one of the homes has a whole complete wall of bookshelves. I've been vocal enough that if we move there, that wall is mine!
