What I would do for a shoe closet like the the ones you'll see below....WHOA MOMMA!!! Don't let your lack of space or $$$ keep you from creating an amazing home for your heels. I actually bought multiple wooden storage shelves from Target that I've stacked on top of one another creating a wall across one side of my closet. I'm planning on painting or wallpapering the inside of the shelves for some added drama.
