A round robin is learning how to make different borders. You measure your center and make it divisable by 3's + 1/2" for seam allowances. Each person adds a border. Everyone does not add 9 1/2". Look back on posts #424-430. We had the option to make the borders 3 1/2"- 9 1/2". And you can see that we did not all make 9 1/2" borders, but varied the widths. Some tops came out bigger than others.
