Bungee cord ball storage makes different balls easy to access and find. Horizontal slats store tall items and plenty of shelves hold onto other toys. A tennis racket gets it's own space using two nails to support either side of the handle and it lays flat against the wall.
I use these in the coat closet to organize gloves,mittens and scarves. In the bathroom linen closet, using a row for each family members health and beauty products. In the hall linen closet for first aide supplies. They're also great in kids rooms for small toys like barbie dolls and their accessories or Matchbox cars and such.
