I am probably no the person to ask. I have sewing machines with dust covers on book cases. Several in cases on the floor of my sewing studio. Of course the treadle is a piece of furniture in my studio. I have another one in my living room as a piece of furniture and 2 more in the back bedroom one a piece of furniture and another is always out. There are also 2 more on the floor in their cases and 2 more in a cabinet. They are not ever really in storage containers or closets they have become a part of the decor of the room only because there is no real space to put there anywhere else.
