Fantastic kit of top thread and prewound bobbins in matching color. Great for embroidering standalone lace designs or any other projects where it's important to make both sides of the design look well. Both top and bobbin thread is made of premium polyester fiber. The kit includes 144 bobbins (6 of each color) and 24 cones of strong poly thread (1 1100-yard cones of each color, to match the quantity of bobbin thread).

The bobbins are 60 wt thread, L size, and plastic sided. Most embroidery machines use bobbins with these qualifications. If you're not sure whether your machine accepts L size bobbins, just measure your original bobbin. If its diameter is 0.8 inches (20 millimeters) and the height is 0.3 inches (7.5 millimeters), then your machine takes L size bobbins and you may buy this kit with assurance. Also, here's a list of embroidery machines sorted by the type of bobbins they use.
