I use the toe separators from pedicures to hold my bobbins. I tape a number to the top of the bobbin and a corresponding number on top of the thread. All of my thread sits in plastic "shoe box" containers and the bobbins sit on top. I try to keep everything in numeric order. So far though I have only used white, blue and green to sew my quilts (all three of them).
HAPPY HOLIDAYS TO ALL
