I had a tiny piece of sugru left when I remembered that a catch had broken on a favorite necklace of my wife's. This turned out to be a very neat little repair, and one with which I'm most pleased: I was able to mould a piece of Sugru onto the last stone on the necklace (where the link had broken off) and then press the link attached to the clasp into it. 24 hours later and Presto! it worked like a dream!
