No it's not Jo Morton fabric, but I have several wall hanging make mostly with Jo Morton fabric and her blocks/designs. I also belong to Jo's Little Women's club and really enjoy it. The fabric used in the two wall hangings were made with one charm pack I won and it was a Moda line called "Wildrose". The one I'm holding in the side picture is from Jo's Little Womens' club and made with Jo's fabric.
I have alot of Jo Morton fabric and I too am on her yahoo group. I read she may not do past JLW #10 .I just ordered her new book and can't wait to get it. Your quilt size is what I would like to do.
