Practice, practice, practice and more practice. Like any art the brain and the hands must be trained to work together. Don't be so hard on yourself. I try to make a lot of Mystery Quilts that are good candidates for FMQ practice. Occasionally I will come across tied baby quilts at thrift stores that I purchase for FMQ practice. I always keep pre-made small rectangles of quilt sandwiches to practice on before beginning the quilting of a top. I highly recommend Leah Day's website for learning FMQ. And I do send my "special quilt tops" LA quilter.
