These DMC cardboard bobbins are storage cards for winding stranded embroidery floss so loose skeins stay neat, labeled, and ready for stitching. The pack includes 56 bobbins, giving you plenty of cards to sort floss by shade family, kit, or work in progress without adding bulk to your storage box. Write the colour number in the label area and keep the cards dry so edges stay smooth and the wraps do not snag when you pull thread.
