Exactly three things; Parachute cord, a sturdy ribbed ribbon, and upholstery thread.
This it the leash-belt combo.
Parachute cord and upholstery thread.
Ends are burned to prevent unraveling.
This is one length of parachute chord with the ends looped round a length and sewn tightly in place so that the cord can still move through the loops, but they won’t fall loose on their own.
The loop on the left is the belt: the folded over loop matches the width of the ribbon by which it’s attached to the collar. The loop around the handler’s wrist doesn’t need to, so it can be shorter.
Here is the collar, with the back attached.
It should fit loosely around the base of the bird’s neck, narrow enough that the folded wings can’t get through.
Collar and belt attached by the back ribbon.
Chest ribbon attached to the collar.
These are all the fixed connections.
Length hasn’t been measured yet. Connection to the belt has to be loose enough to adjust, but not so loose that the birds can tug it.
Here is the finished harness.
Not the same one, obviously, but here is the entire thing in full view.
