Making Due

I am not very good at making circles. I have a protractor, but it only gets so big. So when I needed a large circle to make my zafu pattern, I simply used a dinner plate. For my yoga mat bags, I used a small plate. I'd like to think that there is some thought into form and function and exact size for the product. But sometimes it just comes down to the size of plate I have in my cupboard.
