Your question isn't dumb.... it's an opportunity for us to encourage you. And it sounds like you've already gotten some great answers. My answer is this..... quilt whatever pleases you. There are tons of quilt patterns out there.... every one of them started with someone asking, 'I wonder what it will look like if I put these shapes together in this way'. So, you are about to create something wonderful and new whenever you put two blocks together that haven't been together before. So, go for it....... enjoy your hobby and the freedom to express yourself. And, we all want to see the new creation..... really, we love to see pictures.
