Head pins are a staple item in jewelry design. They allow you to create wire wrapped drops and dangles to be suspended from earring, necklace and bracelet designs. 20 to 22 gauge are the most common sizes; 24 gauge headpins are perfect for wire wrapping beads with small holes, such as freshwater pearls. To use eye pins, you place a bead on the eye pin and use round nose pliers to create a simple wrapped loop. You can attach eye pins to other eye pins, chain to create everything from long chain-like beaded necklaces to drop earrings.
