The largest of these spaces is a spare office closet.
I installed and painted the wooden shelves myself. My sister assisted me in measuring and installing all of the smaller sized wooden rods and metal cups.
The wooden hangers are from OnlyHangers.com and were a great investment. Surprisingly, their cost is on par with the prices that AG charges for their plastic hangers.
The left side of the closet hides a giant stack of mini plastic drawers (by Sterilite). The tower is surprisingly stable, as it is supported on two sides by the closet walls.
The mini drawers are a brilliant find by my sister. Each individual drawer fits on average one outfit, such as a set of pajamas with slippers.
I also use these to store outfits and accessories which do not store well on a hanger, such as swimming suits, towels and accessories.
I was able to store the majority of Isabelle's leotards, tutus, shoes and accessories in three sets of mini drawers plus her dance case.
Finally the right side of the closet has a hidden wooden rod for extra hanger space. I may also put a few hooks on the blank wall space above in order to hang some hats or other items.
