We had a quilt designer at one of our guild meetings last year and she helped me get the attitude of "JUST DO IT!" When she passed around her samples, they were not all evenly stitched. Some were tight, some long stitches. After seeing that, I figured I could do just as well. As others on here have said, when you give your quilt or show it to others, they will never notice the "mistakes" you see. It is like a painting. Some brush strokes are long, others short. Nobody will know. Simply enjoy it and admire your work.
