I have always felt that if you try not to be a perfectionist in this, you have a better chance of succeeding. One of the first times I was meandering, I crossed over a line...I was going to go back and tear it out, when I thought....is anyone but me going to know if one line crosses the other?...can I live with it....yes I can, and I moved on. I also had a hard time with the tension and sometimes the bottom thread would show...a friend told me to line up the tension as best as I could and then just put the same thread in the bobbin as I was using on the top and you couldn't tell. When I finally learned how to sandwich a quilt....holding the back fabric taut and spreading the batting and quilt top over it using lots of pins....I conquered the fabric lop over in the backing....trial and error!!
