I have learned that it's always better to fix a mistake right away when you first see it and not sew another seam across it which will make it more difficult to fix it later. Also learned to cut threads on the finished and quilted quilt top with blunt end scissors so I don't nick the fabric, that a new needle is often the "fix" for sewing machine malfunctions, that choosing my own fabrics often leads to quilts that I really like better than using precuts and all from one fabric line, that I can design my own quilts if I want to and they turn out fine, and that it's a good idea to try some of the suggestions on this board to see if they are better than what I do now. That there are no quilting police and no quilting jail and I can do what I want to do regardless of someone else's rules!
