I did (short gaiters, just above ankle).
PU coated nylon, ordinary elastic band at the bottom, anti-slip elastic at the top, 2 grommets set into bottom elastic and hem on each side, piece of "stiff" braid cord ,one end with a stop knot, other end with a toggle (cordlock)
Simple, not 100% waterproof, but OK in snow or mud, or bogs for a while.
