I roll mine around pool noodles. First I make a cover for the noodle from muslin--I make it long enough that there's about 4" extra which I use as a tag to write the name of the quilt, its size and year it was completed. Second, I roll my quilt around it leaving a couple of inches of noodle extending out one end (for longer quilts you can put 2 pool noodles together by inserting a piece of PVC pipe into the holes in the noodles to join them) and the muslin tag extending out the other. Next I make a cover/bag for the quilt wrapped noodle from muslin- this is just slightly longer than the quilt. I use selvages to tie the cover tightly around the noodle just below the quilt so the quilt won't slip down when I stand the noodles on end. I also tie the cover to the noodle at the other end, leaving the tag hanging out.
Some folks who do this then lay the quilt-wrapped noodles flat, but I don't have room to do that, so I stand mine in a box in a corner of my studio. Have been doing this for a while and by tying the bag just below the quilt where the noodle sticks out the quilt stays in place around the noodle and the ends of the quilt don't get creased since they don't touch the ground.
