I have seen photos of 1700s reenactor/living history folks wearing the cadadh garters tied in a sort of big ornate knot that looks almost like a bow, with lots of loops, like this http://i55.tinypic.com/auftlf.jpg.

How do you tie these sorts of knots and is there historical provenance of such? Or was it more often wrapping it around the calf and tying it in a simple overhand knot?
