After picking up my winter dry-cleaning today, it occurred to me that you all might have some advice on storage:)

All of my sweaters came back individually folded over hangers and enclosed in plastic casing. Normally, I'd just hang them like that in the closet, but I thought read somewhere that it's better to let the wool breathe. I have several options. I can:
-leave them on their hangers, still in plastic
-leave them on their hangers, take plastic off
-take off hangers and fold in drawers
-take off hangers and fold in large enclosed plastic storage box

Is one option better than another? Or is there another option? I want to foil the moths and keep the dust off of my clothes.
