Just two words and a bit of explanation about them will help you to double, maybe even triple, the space in your home now. Those two words are "Go vertical."

FUNCTION FIRST, LOOKS SECOND

That means that when you buy bookcases or other types of furnishing with shelves, make sure these items have five or six shelves. Two or three shelves per item are just wasted space. When it comes to home organization, you want to buy furnishings based on the criteria of function first and then looks second.

So if two items are both of acceptable appearance to you, always purchase the one that is most functional. If one item is slightly prettier than the other but the other item has more vertical shelving, cubby holes and nooks, choose that second item. The peace-of-mind you'll get from having a more organized home will be much more valuable to you in the long-run.

DON'T FOLLOW YOUR EMOTIONS

Always remember that stores want to sell to you based on your emotions. That's a fact. Most marketing research agrees with that statement. If the seller can hook your emotions, they're closer to a sale. For example, you see a pie safe cabinet that's outrageously priced but beautiful. So you say to your spouse who's shopping with you: "Oh, look at that pie safe cabinet. It's gorgeous. Look at that blue color. It's a little a high priced but maybe we can get it on credit..."

Stop right there!

As a smart shopper (and a smart home organizer), you want to buy based on what your brain tells you. So for example, now you look at that same pie safe cabinet and say: "Oh, look at that pie safe cabinet. It's gorgeous. What a pretty blue color. But we need something a bit more functional. That cabinet only has four shelves and the one next to it has six shelves and is cheaper. The second one is maple stained, not blue. But that's okay. It's still a handsome piece of furniture and it's more functional. We'll get more space to use in our home and more product for our money."

Use your head, not your heart, to make decisions about furnishing items for your home. Then you'll have functional home furnishings that double your home storage space. Think like a home organizer versus a home decorator. Think function first.

ANALYZE FURNISHINGS IN YOUR HOME NOW

Look around your rooms. Do you have a two shelf horizontal bookcase? Do you have a tiny three shelf freestanding pantry in the kitchen? Do you have a little three drawer jewelry or lingerie armoire in the bedroom? Go room-to-room and make a list of any type shelving unit like these or others (e.g. microwave cart, television cart/stand, etc.)

Unless these items truly hold sentimental value, it's worth selling them to a used furniture store or at a yard sale for a bit of cash. (I'll tell you why sell in a minute.) Or spend a few bucks to put an ad in your local "Pennysaver" type newspaper advertising the item for sale.

SELL HIGH; BUY LOW

Then negotiate with the potential buyer so you get the best price possible for the item you're selling. That means you must suggest a price that's beyond what you expect to get. Why? Because these days potential buyers will almost always ask you to come down on the price. In fact, I guarantee three out of four buyer prospects will try to get you to lower the price. So start high so they feel like they're negotiating the price down.

Why sell the item in the first place? Because you want to use the cash you make to upgrade to a taller unit of the same item. If you watch those home decorating/organizing shows on television, you may recall that there is a certain show that uses just this strategy. They have a big yard sale with all the participant's useless items and use the money to upgrade to more useful and stylish items for the same space in the home. The difference in the home is usually extraordinary at completion. You're striving for a similar method and outcome.

NOW DOUBLE YOUR SPACE

You want to use the cash to buy a comparable piece of furniture that serves a similar function as the piece you just discarded. You can even put the new furniture piece in the exact same spot where you had the previous piece. But make sure the new piece of furnishing is taller with more shelving or nooks. Remember, the big two word secret in this article is "go vertical." So in the end, you'll use the same floor space in your home but double its storage capacity.

And when replacing your items with comparable items, don't hesitate to buy used furniture (even from the same shop you sold yours to). If it's in good shape in regard to quality (e.g. no rotting, flimsy wood panels, etc.) but not exactly your favorite color, you can fix that. Get a four dollar can of spray paint and a primer spray coat and change the color. Or get creative such as use some pretty contact paper to redo the outside. And one final piece of advice: Don't forget to negotiate when you're the buyer!
