I think Jan's method would probably be easier to learn. Sharon is certainly correct that the quality of the mitered corners is a major factor is judging. I have certainly heard this on quilts of mine and I have had more than my share of blues. Looking at Sharon's corners, I think mine come to a better point, probably because I cut the batting out (on a 45* angle) to make space for the binding to come to a sharp point. I have not used Sharon's glue method and might well try it for a flatter edge. I will re-emphasize that having the binding full and exact corners has made the difference for me between blues and no prize several times. I use a different method to achieve the same result of exact connections on binding ends. They are important too.
