These DMC plastic bobbins are reusable bobbins for winding embroidery floss, helping stitchers keep colours untangled and quick to find during a project. Each pack includes 28 bobbins, making it easy to group floss for a single pattern or build a tidy long term library in a case, box, or ring system. Label the bobbins before winding and avoid overfilling so the wraps stay flat and the bobbins stack and store without catching.
