Giggles! I love the Donald Duck theory! I have seen some pics of antique quilts that have very wide borders and others that have none. Hmm, those quilt makers were not formally trained by the --cians, or ----ists, just used what they had on hand or to make the size wanted/needed. I, personally, have done all ways. Never once did a theory question enter my mind at that moment. In actuality, I imagine everything we do is based on some theory.
