I got this great gadget last week and I love it. It holds your bobbins in a tower configuration. Before, I kept them in a little lucite box that often flipped or got knocked around. With the bobbins in this thing, if you knock it down they don't go flying all over!
It is easy to slip them in and out. You can easily see the color of your thread. And it is really easy to organize - I have empty bobbins in the dark green section on the bottom, and bobbins with thread on the yellow sections. I might have to get another to keep the Singer bobbins in for my embroidery machine.
I got mine from Keepsake Quilting (click on link above), but it is designed by Nancy's Notions. I give it a big thumbs up!
