Another thing I was never comfortable with was how bail wire wraps were usually ended, most of the time on the outside of the bail. At least most of the time they were covered with other wires bent over them. Since only one layer of half round wire was usually used to secure bail wires, there were always going to be two loose ends. Because half round wire is so soft, in many cases those ends could easily be snagged and pulled away from the pendant. Another issue with the softer wire was that one layer of half round wire did not really provide a strong wrap.
Before shaping the bail wires: Leaving at least a 1" tail of half round wire and starting on the back base of the bail wires, wrap the bail wires together, generally 4 to 5 wraps and ending on the back. Try not to overlap the wraps but have them nestle tightly side by side. DO NOT CUT THE WRAP WIRES OFF!
