Decided to go for a direct attachment to the frame using the cow hitch. When I went to tie the knot, I realized what I thought was a fat stop knot was really an overhand knot tangled around a smaller overhand knot. Seems like Prism tied the bridle directly to the frame with an overhand knot, and used the other single overhand knot as the stopper. I stuck with the cow hitch anyway.
Thanks for the responses!
Josiah Either way works....prism's method is the overhand knot OVER the rod with the little knot at the end as a stopper as you said....but either way will work just fine....
keep in the back of your mind though that if you are ever doing anything with the bridle and measuring the length of each leg you will have used up a little more linear length of the bridle.....so measurements might be slightly off....nothing bad...just a reminder for later...
