Below is a super cheap (64 cents) pair of those wrap around garter flashes that I fashioned from some cotton strapping, I bought at Joanne's fabric store.

I have 19" calves, so I bought 4 yards at 16 cents a yard. I wrapped them three times around my calf at the proper height, left a little to hang down and trimmed off the excess. I then un-raveled the ends and frayed them a bit, took a couple of stitches with red thread to keep them from un-ravelling further, and Presto-Change-O a pair of wrap aroung flashes.

The cotton ones seem to work just as well as the higher priced wool types, and suits my frugal nature. I saw green, black red, blue and white straps available by the yard.
