We found this huge pile of wonderful, old steel ball chain. It is available pre-made for you in 28" continuous necklace or you may buy it in 8' lengths so you can make your own $12 per strand). The balls are hollow with a seam so the individual ball may be squeezed apart to be joined. The extra large balls are bigger than a B-B. Wonderful when elements such as old keys, brass tags, old ivory rings are hung on it.
