I use the soft plastic bobbin boxes (JoAnn's $3-4) - have one for my Singer, one for my Bernina and one for embroidery threads. Most of my threads I store in a plastic stacking bin; the embroidery threads are bottom up in plastic bins as well (don't like the dust that accumulates if they are left out or on a rack. I use the nick on the older spools to keep thread from unraveling. Was really excited when I saw how they revamped the new spools The bobbins I make sure are wound back up when I place them in the box - most times they will stay that way.
