Hi Andrea, Put 2 poles on top of each other. Make the top pole high enough to just get the hanger over the bar. Next, put the second bar just under where the top one hangs, so the clothes don't touch. Hang the second row there.
Do what we did: Watch local auctions or online buy&sell sites for an antique wardrobe. We bought a gorgeous old wardrobe with clothes rack and some drawers for less than $400 and it really adds style to the room!
