I do not ( store) a work in progress- it is out, possibly all over the sewing room. If I stop working on a project it becomes a ufo and is put away. Depending on what stage it is in it May be in a drawer or a box or bag. Also depends on why I stopped working on it. If I may never finish it it might be packed away for a long time- if I plan to finish it , it will stay fairly close- a drawer or a shelf
