Someone told me that the Amish ladies intentially put in a mistake (block backwards, some piece of material in backwards, etc.) because they believe only God is perfect. I on the other hand don't have to try, I have yet to made a quilt that doesn't have a mistake somewhere. I tries to perfect my hand quilting to make those little bitty stitches and when I got to that point, the arthritis in my hands soon made that impossible. I am satisfied with each quilt as being the best I can and they are all beautiful, especially to the ones I give them to. Enjoy your hobby, don't get in bondage to it.
