In my rush to learn new things, I often make pieces instead of a finished project. I have boxes of polymer canes waiting to become something. I have tiny silver leaves and flowers waiting to be cured and added to something. There are pieces of old jewelry in one box that I know I will use someway. It's much the same as George Carlin's "Stuff". https://www.youtube.com/watch?v=MvgN5gCuLac
Once in a while I actually take a piece and turn it into something finished! Truthfully I generally finish my jewelry as I make it. But not always.....as the boxes filled with pieces attest!
