Our Master Bedroom has two closets, which is two more than most houses the age of ours. One is original, one was added probably in the 50's. The original one is located between the chimney and stairs and is about 7' deep and 30" wide. Before we even moved in, I told R this would be his closet. The other closet is a more "normal" size, about 30" deep and 6' wide. I hang most of my clothes up, plus need a lot of storage, so that closet became mine. I painted/cleaned my closet in October of last year, because I couldn't stand living out of boxes (I'm one of those people who need to see all their clothes in order to choose one). R, however, was perfectly content with his clothes in boxes. Because he didn't care, cleaning and painting his closet kept moving farther and farther down on my list of things to-do. In July I had finally had enough. We were about to go on vacation and I hate leaving the house messy when we're away (it's one of those things my mom ingrained in my head when I was little... you never want to go away and come home to a messy house). I had finally had enough of the boxes of clothes piled up in our bedroom.
The closet has 2 shelves in the back (about 24" deep). One these I put some long-term storage, pillows, and some of Ryan's stuff that he rarely uses. Underneath the bottom shelf (which is about 3' off the floor) I put our large suitcase and filled it with all of our dufflebags, backpacks, etc., so now when we're packing to go somewhere everything is in one place. On top of that I put our big, thick winter comforter in it's bag. (That's another thing I'm very excited to have a place for... It's white and light blue, and when it's too hot we've just been kicking it onto the floor. It basically spent the whole summer on the floor which means it got dirty from the floor and from the dog that decided that it was a new big huge bed we bought for her). Along the walls are old hooks which I was originally going to replace, but then decided just to paint them. I hung R's belts and ties on them.
Because the closet is so incredibly deep, there are 2 hanging rods. This would not have worked for me because I need to see all of my clothes. For R though, perfection! On the back rod I hung all of his winter clothes and on the front rod, all of his summer clothes! So now when he's looking for something, they're organized so he's not looking through sweatshirts for a polo shirt, but also if we have a cold early fall day, he still has the option to grab a long sleeved shirt if he wants. It also means that season-changing will be easier because rather than spending a whole day unpacking and packing clothes (like I do for my clothes), all I have to do is switch which rod they're hanging on.
