Judy Mathieson's Mariner's compass book also teaches you how to draft a compass, any compass no matter how many points. Because you already figured out that there is a point at every 36 degrees all you will need is a compass and a protractor and Judy's book and you will be able to draft this out yourself to any size you like. It is absolutely gorgeous and looks like it may have been your relatives Heirloom quilt. It is just beautiful.
