I'm looking forward to the pics of them in use!

I've been considering making my own garter ties as well. They just look more traditional and add some flair to an outfit. But man, they're pricy! I've been thinking of braiding my own, with maybe a 12-part flat braid out of wool yarn. Your idea seems pretty good, although I'd like to see the finished product tied in place with hose.

Is the ribbon not too slick to hold itself tied?
