This is "spool-knit". One continuous strand of very thin sterling silver wire woven over nails stuck in a spool and threaded through the hole and out the bottom. You did that with a spool and yarn when you were a kid, right? Haha! This necklace was woven with 7 nails, so it's thick and substantial, it closes with an easy spring ring, and it measures about 22" long. If you have pendants with really big bails you could wear them on this, but it's fantastic as a stand-alone accessory, too! I make a similar chain woven with 4 nails--it's thinner and more delicate, but equally eye-catching!
