I am embarrassed to say I have had "parts" (meaning partially constructed jewelry components) buried on one of my work tables ... oh, I'd say for a few years now .... that were in need of finishing.
I had soldered all these buttons into nice neat little glass boxes and soldered bands around other buttons. Pretty wonderful "parts" in themselves, but that's as far as it got.
Last week I went to a used jewelry sale put on by the Livonia Senior Center not far from me. I bought a necklace made of chain and small pearl beads for $1, took it apart and had more than enough to put all my parts together and make 2 necklaces. I think they look pretty wonderful worn together as well.
