I'm fairly new to quilting, but I've said repeatedly to my quilter friend at work that there are just so many ways you can make a block and I keep seeing the same things over and over. So, I understand completely what you are saying. Making a square in a square a few inches bigger than the last person doesn't make it a new design. With that said, I also see wonderful and inventive quilts that look fresh and new. What makes an original? I guess someone to call it original! lol. Keep designing and enjoy the process.
