I guess I am one of the lucky ones in that I just "eyeball it" and watch where that is on my presser foot and sew, sew, sew. And leaders/enders really threw me for a loop; I never did get the hang of it. But I just piece with my SS machines only. One of my quilting classes had a special session on it; and that day was wasted on me. And just for a clarification here, I failed knitting two years in a row at camp. Most wasted $40 of my life.
