Room for storage is a problem for me too - storing frames that I'm not currently using. I've considered using a wall mount rack to hang keeping things off the floor (laundry room.)
Maybe DIY wood rack...
...or using a wall-mount tire rack with a piece of wood across the bottom -wood covered in scrap piece of carpet to protect frames from scratches on the bottom. Something like this in following link?http://www.homedepot.com/p/Proslat-28-i ... /203477820
Spare floor room is a problem for me - for that reason I'm trying to think of something that I can hang above washer/dryer...even something to suspend from the ceiling.
