As your children get into their teen years, it becomes more and more necessary for them to have a space to do homework in. Giving them a board to pin notes, etc. to will help them keep organized (as well as providing a space for them to express themselves without going crazy over your walls!). Make sure you talk to them about internet safety if they have a computer in their room though!
Kids' Closets: Hanging organizers are the best use of a closet rod — and they can be hung from the top of a door or the bottom of a wire shelf if you've removed the rod. These organizers are canvas columns of compartments that can be used to store a wide range of items, from clothes to shoes to stuffed toys.
