OK so I decided to be bold and try the French Braid pattern. I am finding the directions so confusing. I can usually figure these patterns out so I am not totally without a few good brain cells or so I thought. Was going to say forget it but the material cost too much and I hate to give up. This one might make me. Anyway the pattern I am trying to make calls for a 15" base triangle. I don't have a ruler that does a 15" base nor can I find one. Will someone please help me??? I just want to get through this and will never do it again. Thank you.
