Thanks for the advice! I too have made many sacrifices thinking my work was fine until I took closeup pictures, saw the marks, and had to trash it. I've wasted much time and a lot of wire. I have a plastic head square shaped tool that I use to make spiral turns, however, the small loops and hooks are still a problem. I've tried wrapping the tools with plastic tape, but that wears off and leaves a gummy mess on the tools. Also, as stated above, if you grasp the wire past the part you are turning, then cut off the piece where you grasped it and use your fingers to finish it, that works, but gets tedious. So, until someone invents a tool that will solve these problems....just be extra careful.
