The first rule of quilting is...There are no rules! Your quilt, your ideas, your way. If a design pleases you, go for it. The so called "quilt police" can go take a flying leap. Be creative and enjoy the process. This is what I'm telling myself after 10 years of quilting. We shouldn't worry about what anybody else thinks about our creations as long as it pleases us. I love the pink block thrown in there only I personally would have to do more than one. Love your designs.
