I just have mine stacked in my basement. They are all soft cloth cases. You can roll several of them up in a ball and put them in a large 16X16 zip lock bag. I have stored them that way before. They never got moldy. eightbore has a good idea too- just storing them in a Rubbermaid container. That will keep them clean and dust free. You can also hang them in a closet by the loops on a plastic coat hanger. I have done that before, too. My hard cases are just standing in the corner of the room. Good luck!!
