Right and wrong are harsh judgmental terms. And most quilters will say that however you put your blocks together in your quilt is your decision. But sometimes with some quilts there really IS a difference!
When I showed the windmill blocks to Charlene Higgins, one of the quilt instructors at The Golden Gese quilt shop in Concord, New Hampshire, she loved it! But she was quick to point out that the block needs to go together as light-to-dark opposites to really look good. Otherwise it looks lopsided.

Tonight was my guild meeting and I had fun reconnecting with some friends, enjoying the featured speaker, and showing off my Calliope Music quilt. I also borrowed a quilting book about borders from the guild's library. On the way home there was rain and patchy ground fog and I was very grateful that the temperatures remained above freezing, so no black icy spots, just rain. It was 9:30pm when I got home, so I had missed the Hoarding show that I like on TV. Oh well! Every guild meeting is better than TV anyway, right?
