I was raised with the notion that "if something is worth doing, then it is worth doing well." I go at different paces when making a quilt depending upon the difficulty of the project. For me, it is done when it's done. I've taken classes where other quilters just run the fabric through so fast as if they were Evelyn Wood (speed reading teacher for those who may not be old enough to remember) students. Nine times out of ten their seam widths vary and don't match up. I just can't justify sacrificing quality for speed.
