The Molecule Lochrose (Swarovski Elements Sew On Stones) can be applied by hand or by using a domestic or industrial sewing machine. When sewing the Molecule Lochrose, synthetic multifilament threads with a thread count of Nm 80 are most suitable because of their abrasion resistance. Monofilament and pure cotton yarns are not recommended due to their limited abrasion resistance. Please make sure that the transport system is deactivated to avoid any movement of the fabric. The 3708 Molecule Lochrose Sew-on Stones Swarovski Elements is available in sizes: 8x8.7 mm and 12.5x13.6 mm
