The closet in our spare bedroom is huge- it takes up an entire wall (which is terrible for furniture arranging, let me tell ya)! Unfortunately, it only has one dinky wire shelf inside, which means all my c-r-a-p is simply piled on top of itself and lacks any rhyme or reason at all. I'm thinking a simple DIY shelving system would be the answer. Amy from The Idea Room scored big on some old lockers that she spruced up, but still had an empty space in need of shelves. With a little measuring, cutting, and assembling she was able to create exactly what she needed- she even had a spot for her ironing board.
You can see how Amy did it all at The Idea Room.
