So, about halfway through, I ran out of the copper wire I was using. I could have gotten more, but I had a spool in the same gauge of magnet wire, which also happened to be reddish. Reddish, festive and xmas-y, although it wouldn’t go very well with the green and purple I was using before, so I changed the base cord colour to white. I was going to use some pink too, but forgot as I got into the flow of construction. The final knot including the hanging thread is in the picture to the left, and to the right is the knot in it’s gift packaging (little organza bags from eBay).
Lastly is an image of a couple of the almost completed ornaments, missing their bottom coils, but showing some of the variety in the tightening over the centre bead.
