I rebuilt my braided false crotch using a single piece of rope. It tested well for strength. I'm rejecting it as impractical because it's too much weight compared to a typical bark saver. Anyway if you're interested in playing with it here's how it's made from a single piece of rope.
Start braiding on one end and continue until it's done. The ends are bound with electrical tape but it could be done w/whipping twine. Before finishing off the binding at the loops I cut the two free ends at an angle to make a smoother transition from the loop to the braid.
