Each bobbin provides 50 yards of durable, washable, and colorfast sewing thread, making this set a must-have addition to your sewing supplies, perfect for both novice and expert sewers. Class 66 bobbins are unique bobbins that are curved on the top and bottom and fit mostly older SINGER® machine models. Compatible with many SINGER models and other top drop-in bobbin sewing machines, these bobbins offer great versatility. Please consult your machine’s manual to determine compatibility. In machine sewing, the bobbin thread forms the bottom part of your stitches, working with the top spool thread for strong, consistent stitches. Made from high-quality plastic, these bobbins ensure smooth thread winding and unwinding, preventing stitch irregularities and machine jamming. Using SINGER Bobbins is simple: wind your thread onto an empty bobbin, ensuring it is correctly seated in the bobbin winding tension disk of your machine. For best results, use bobbins that match the class/style of those that come with your machine and wind thread onto empty bobbins only, ensuring proper tension. Replace any bobbins that become chipped, bent, or damaged. Whether you're creating clothing, quilts, or DIY home décor, the pack of 12 SINGER Class 66 Transparent Bobbins, pre-wound with black and white thread, delivers professional results with ease. ## Features - Set of 12 Black & White Threaded Bobbins: Includes 12 Class 66 transparent bobbins, pre-wound with 50 yards of 100% spun polyester thread, featuring 6 bobbins with black thread and 6 with white thread, ideal for a wide range of sewing projects. - Versatile Compatibility: These bobbins are compatible with a wide range of sewing machines, including select SINGER models and other top drop-in bobbin sewing machines. PLEASE CONSULT YOUR MACHINE MANUAL TO DETERMINE COMPATIBILITY. - Durable Material: Made of high-quality plastic, these bobbins are designed to withstand regular use without breaking or wearing out easily. This feature ensures that you get a reliable and long-lasting product that you can trust for all your sewing projects. - Thread Management: Using partially wound bobbins can lead to uneven thread tension, tangling, and thread breakage. It is important to use these Class 66 bobbins only when fully wound. The bobbin's transparent design allows you to see when thread is running low, ensuring that your sewing projects remain smooth and hassle-free. - Correct Bobbin Size: Consult your sewing machine's manual to ensure that you use the correct bobbin size. Using the wrong size may lead to damage to your sewing machine and cause thread breakage or uneven stitching. Never substitute the recommended bobbin size. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #277,342 in Arts, Crafts & Sewing ( See Top 100 in Arts, Crafts & Sewing ) #983 in Bobbins | | Customer Reviews | 4.6 out of 5 stars 629 Reviews | ## Product Details - **Material:** Plastic - **Brand:** SINGER - **Color:** Transparent - **Item Weight:** 0.09 Pounds - **Item Length:** 5E+1 Yards - **UPC:** 075691300272 - **Global Trade Identification Number:** 00075691300272 - **Manufacturer:** Dyno Merchandise ## Images ![SINGER Class 66 Prewound Plastic Bobbins, Transparent – Black & White, 50 Yards Each, Washable and Colorfast Polyester Threaded Bobbins with Storage Case, 12ct - Image 1](https://m.media-amazon.com/images/I/51uUlF9xVuL.jpg) ![SINGER Class 66 Prewound Plastic Bobbins, Transparent – Black & White, 50 Yards Each, Washable and Colorfast Polyester Threaded Bobbins with Storage Case, 12ct - Image 2](https://m.media-amazon.com/images/I/613gQDK379L.jpg) ![SINGER Class 66 Prewound Plastic Bobbins, Transparent – Black & White, 50 Yards Each, Washable and Colorfast Polyester Threaded Bobbins with Storage Case, 12ct - Image 3](https://m.media-amazon.com/images/I/61VI36+Yv4S.jpg) ![SINGER Class 66 Prewound Plastic Bobbins, Transparent – Black & White, 50 Yards Each, Washable and Colorfast Polyester Threaded Bobbins with Storage Case, 12ct - Image 4](https://m.media-amazon.com/images/I/81kv66FlijL.jpg) ![SINGER Class 66 Prewound Plastic Bobbins, Transparent – Black & White, 50 Yards Each, Washable and Colorfast Polyester Threaded Bobbins with Storage Case, 12ct - Image 5](https://m.media-amazon.com/images/I/51fW+HTFIML.jpg) ## Frequently Bought Together - SINGER Class 66 Prewound Plastic Bobbins, Transparent – Black & White, 50 Yards Each, Washable and Colorfast Polyester Threaded Bobbins with Storage Case, 12ct - SINGER 04801 Universal Heavy Duty Machine Needles -2 Pack - Sewing Machine Needles, Pack of 50, for Singer, Brother, Janome, Varmax and Home Sewing Machines.
