The Singer Plastic Bobbins is designed for use in Singer Futura Embroidery Machines series 2600s, 3900s, 7400s, 8700s and Izek 1500. The bobbins come in a plastic storage box, which is reusable and easy to store. Refer to your sewing machine's manual to ensure you use the bobbin in the right size. Use the transparent bobbins beneath the needle plate in automatic sewing machines to wind the thread for embroidery projects. Ensure that you do not add a thread to a partially wound bobbin, as it may be uneven and cause the thread to tangle or break.
