You always learn by the mistakes you make. That is what learning is all about. I think it was awfully brave of you to tackle this type of quilt as your first one. My DH husband said it wasn't awful, but quite impressive for your first one. I think you did a great job. A big pat on the back. I always look at a quilt top closely when I finish and pick out what I don't like about it. Then I concentrate on ways to make it better next time. Please finish it and show us when you are done.
