Introducing B Bobbins: Pre-Wound with 80 wt. DecoBob™ Thread for Bernina Machines
We’re excited to launch a brand new product made just for Bernina users: B Bobbins pre-wound with 80 wt. DecoBob™ thread. These bobbins combine the precision of ultra-fine thread with the ease of pre-wound convenience so quilters, embroiderers, and sewists can experience smoother stitching and better results from start to finish.
Why Choose 80 wt. Thread?
The thread you use directly impacts your stitch quality. That’s why 80 wt. cottonized polyester thread has become a favorite for its strength, softness, and ultra-fine profile. This thread delivers crisp stitch definition and allows you to create highly detailed, flat, and refined work with significantly less bulk in your seams.
Whether you’re piecing intricate quilt blocks, stitching embroidery, or working with layered fabrics, 80 wt. thread supports smooth consistent stitching and minimizes tension issues. It also pairs beautifully with a wide range of top threads including 40 wt. for bold detail or 50 wt. cotton for perfectly flat seams.
What Makes B Bobbins Unique?
Each B Bobbin comes pre-wound with 200 yards of 80 wt. DecoBob™ thread. This means no more winding your own bobbins or struggling with uneven tension. You get longer sewing sessions, fewer thread breaks, and beautifully smooth stitches every time.
Because 80 wt. thread is so fine, it fits more yardage onto each bobbin so you spend less time reloading and more time sewing. It is ideal for piecing, quilting, and embroidery projects where precision and efficiency matter most.
Built for Bernina Machines
B Bobbins are engineered specifically for newer Bernina sewing machines. They offer a perfect fit and optimal performance for the following compatible models:B990 790 PRO 790 PLUS 770 QE PLUS 780 770 QE E 740 735 Patchwork Edition 735 590 E 570 QE 570 QE E 540 540 E 535 E 535 485 480 475 QE 435
To get started, thread your machine as usual and insert the B Bobbin. Then head into your machine’s settings, search “bobbin,” and turn off the bobbin thread sensor by disabling the bobbin thread indicator. That’s it. You are ready for smooth uninterrupted sewing.
More Versatility Less Hassle
The B Bobbin works in either the black or yellow bobbin case depending on your project needs. You can pair 80 wt. DecoBob™ with any top thread such as Fabulux™ for bold embroidery or Tutti™ 50 wt. Egyptian cotton for piecing and quilting. When used with the right stabilizer such as Total Support™ your stitches stay clean even and beautifully defined.
Experience the Difference
Bernina bobbins already hold more thread than standard bobbins. When pre-wound with 80 wt. DecoBob™ they last even longer. These bobbins give you all the benefits of sewing with finer thread including stronger seams, reduced bulk, balanced tension, and a more polished finish.
Now with the introduction of B Bobbins Bernina users can enjoy WonderFil’s pre-wound performance in a format made just for their machines. No winding. No guesswork. Just better stitching from the very first seam.
