Unfortunately, I've tried those options and they aren't working for me. I have one of those cube hang-y things from Ikea. The crinolines just don't fit very well in them. And when I've put them in boxes, they just don't look very good after I've taken them out. I don't have much space in my apt for an another zippered closet box. I guess I'll just have to keep looking. Sigh.
I hang my crinolines from a skirt hanger in my closet. Towards the front, where they have the room to be full. They seem to be ok, and there has been no type of damage to having them this way in the closet. Occassionally, when I have an extra dry cleaning bag, I'll hang that over the crinoline. Hope that helps.
