These earrings are made with high quality 100% cotton thread (Lizbeth #20) and glass beads. The beads are withing the thread, no glue is used, so they will never fall from the earring. It's an original design. The earrings are around 1.5" to 2" in diameter. The jump rings are made of aluminum and the ear hook is Stainless Steel, nickel free. The technique is Tatting Lace. It's one of the few laces that can't be machine-made. When you buy a "tatted" work you're getting a one of the kind work of art! I can make them in other thread colors and beads. Color may vary (lighter or darker) from the photo due to monitors settings.
