Why didn't I think of this before! Really, Why?! I have spent some serious time and effort on organizing bobbins. I know crazy when so much of my world is neglected and in chaos. But bobbins and thread all messy makes me nuts. I also am a bit OCD about my thread and bobbin matching when I sew and can't stand to wind one color over another color on a bobbin. I have tried that and eventually need the color under the one on top. Then I have the dilemma do I unwind the top color and waste all of that thread or just wind over the top color again and make a rainbow out of this thing. I know if only I had used my obsession for curing cancer or world hunger. Sorry, all wasted on bobbins.
Find a shallow container. This is one I found at a thrift store. Mark the width on a kitchen skewer.
Cut the scewer at the mark. Measuer up and repeat with the rest of the skewer. My box is 4 1/2 inches wide so I was able to make two out of one 12 inch skewer.
