I see alot of people ask about these. Since most people piece in 1 color, why not just get extra bobbins and wind 15 or 20 of them at one time? That way you will have another one to go to right away. When they start getting low just stop and wind a bunch more. I got 50 bobbins off e-bay for $5.00 with free shipping. I would rather have the money for something else quilty. :D
