I Knit as well a quilt, and was told that if there is a mistake, that usually you are the only one who knows it and that a mistake shows it is hand made, not made by some machine. My knitting usually has a mistake in it, not intentional, and some of my quilts are not professional looking, but they are all welcomed. The person getting them does not see the mistakes, only I know they are there - as it should be.
