Hi Leigh--I just read your article, with its recent revisions, on quilt codes (http://hartcottagequilts.com/railroad.htm), and I want to thank you for such a careful and detailed piece of work. I know how much time this must have taken. This is such an important topic, and you have done such a good job of treating the topic seriously on such a wide variety of levels. We needed this! Thank you! Judy Wellman
