Thank you! I make continuous loops with a locked brummel, which leaves a little bump but I don't mind, but it gets around the bury-only method that can slip when not under load.
I've toyed with making one long dogbone and sewing in the larks heads where it attaches to the hammock. In this case, instead of the larks head at the turtle, you're right the butterfly will hold better...I'll give it a try.
