The Amish believe there should always be a mistake in your quilts....although it would take a magnifying glass to find theirs. In my case my mistakes stick out like a sore thumb but I don't enter my quilts in shows nor care whether they are absolutely perfect or not. My quilts are quilts of love and intended to be used and worn out for the benefit of the person I've made them for. We all decide what we can live with and what we can't so that is really the question you must answer for yourself.
