This one starts near the bottom. I had worked my way through one side and the top before I realized I had added too many rings to the first side arm. My first thought was to cut it off and start over. (Later, of course. I was easily discouraged, I'm afraid.) However, I talked myself into cutting out and salvaging the project. My choices were to cut out a small amount and lengthen all of the arms or go back to the spot where I added the first additional ring. I chose to do the latter and got it finished before I went to bed last night. It feels wonderful to have started and completed a project. I'm going to find some more shuttles that need emptying and start another.
Thanks for the welcome and the inspiration.
