I really like this idea for a playroom and it would be really easy, the shelves are sold at most wholesale stores...I've seen them at Sam's and Costco.
That's a bookshelf. This may be my favorite new idea. But one question? What man has this many shoes???
This is a great way to organize--by category. Pants, skirts, long sleeve/short sleeve shirts.◦
And I can't find the image I had for this, but I have to say, nothing makes a closet look more organized than wood hangers. They sell them by the box at Target (online they're $20 for a box of 30). Wood hangers make it so that all the clothes hang on the same level, that alone really makes a difference.
