Got extra money to spend on your home? Consider new shelves and racks.
And no, I don't mean that you should just buy more and more and more until there is no more floor space to walk on. But as you accummulate junk and stuff, and as you throw or give away some of your possessions, and as your needs and preferences and lifestyles change, so should your organizational units.
Football trophies that once occupied TV shelf space may have to give way to new pictures, or vice versa. Or you may have to get a separate cabinet just for those. You may even start considering floor-to-ceiling shelves, not only to create height, but also to house all your books and CDs. New shelves may even be called for to accommodate modern gadgets with their less bulky designs and twice as many cables/paraphernalia.
So always be in the lookout for moe efficient shelves that suit your needs. And yes, do consider having old ones refurbished and revamped to serve the same purpose.
