I definitely enjoy the precision piecing part of quilting. BUT if I've ripped twice and still have trouble, I accept the situation knowing that we are working in a soft medium, not wood or stone, and that some fabrics just have a "mind of their own" (probably due to the weave/fiber content/thread count/coloring/even humidity or insanity!)
And you know what, in over 30 years of quilting I am unable to go back and find those "faults' in my finished quilts.
