Lovely quilt.
Early in my time as a quilter I was watching a program suggesting that one grab a random piece from a paper bag for each placement. My DH, who was wandering through at that time exclaimed that it was a stupid idea and shows a lack of trust in one's own color selecting ability. We both love scrappy quilts but random is not the name of our game. We frequently confer on layouts, getting very pleasing results. IMHO, random ends up being splotchy.
