ok I used a magic templet. I am not sure if she is still selling them, I would check it out or see if anyone has one to sell you. www.brilliantbowmaker.com
I tried to make one with out it to show you and couldn't. This is what I made with her templet. It is worth the money and its quick, I think its like 30 bucks, but sooo worth it. you get a 7/8ths and 1.5 template and a little binder with EVERYTHING you need to know with it.
