Since I piece with Aurifil I wind 5 or more bobbins of the same color and keep them in an empty rx pill bottle. Each pill bottle contains a different color, tan, black, white, etc. The other not basic piecing colors go in one of those donut bobbin holders.
My Gammill bobbins are another problem...I wind the colored thread of those bobbins and if I don't use it all I store them with their cone thread on a moveable 2 side pegboard set up my dh made.
