Is there a trick to the first crimp? I know you are suppose to keep the wires on opposite sides when you make the first u shaped crimp,,,, but I fight it every time. I can keep the tails apart, but the clasp wants to twist and that makes an x when I want them on the outside edge!?!? I'm new at this,,, is there a trick??? (instead of frustration and waisted time?!) If you would share your tricks,,, it just might be one of the most useful things I could learn! Thanks
