Using butcher's twine, tie up the roast, using a simple slipknot finished with a half hitch every 3 inches.
Take a half hitch in your rope and place it over the head of the horse where the bridle brow band sits.
I tied a split rope bowline, with a half hitch or two on the tag end just for good measure.
The half hitch is attractive to the eye and so is used decoratively.
