Legal cabinets usually aren't deep enough. If you have an extra bed that is rarely used you could put several layers of quilts on top; then rotate them out for using as a bed cover. When I entered a quilt show they required our quilts to be in a pillow case. I made my cases bigger so as not to scrunch the quilt and longer to fold under. I put the name and date on the end and now its easy to pull out the opening when looking for a quilt. This has allowed me to store them on closet shelves and not worry about dust. Now every quilt will get a case as soon as its finished.
