Everyone has given you good advice, I can't really add to it but I will say that I don't worry so much about my stitches looking perfect. I'm happy if I don't have skipped stitches or eyelashes. I know I'm not making a show quilt and the recipients of my quilts don't care if the stitches aren't perfectly even. We are always our own worst critic. Once I relaxed and gave up my quest for perfection, deciding that done is better than perfect, my quilting actually got much better.
