I love the plastic tubing idea. This board has taught me something that has helped with the bobbin overload problem, use them up when piecing. I realized I have bobbins from things I did years and years ago. I know I will never match that bobbin to the right thread to make something again in that color, so I have been using them up. That said, I do keep my embroidery bobbins separate and extras wound, so the plastic tube would be very useful there.
