I keep mine in closets, on beds, on a rack. But I also have bought some pool noodles (the foam kind) which I have covered with muslin before rolling quilts onto them. If the quilt is wider than the noodle, I have taped (using archival tape) two together and cut them to fit. I have rolled more than one on a noodle, too. Then I have stood them up in a closet. I checked with our state historical society about this, and the registrar/curator said it should not do any damage to the quilts.
