My mom and I went to a retreat last year and had precut fabric for a Queen size quilt. About half way through the class I brought to the instructor's attention the fact that she had her measurements incorrect and the entire class had actually bought and cut enough material for TWO Queen size quilts! And, we had sewn about half of it together, so instead of leaving with one finished quilt top, we left with two half finished quilt tops!! And, yes, they are still half finished!!
