If you used the teflon fabric for the bottom, or used the InsulBrite batting, all you'd need to do is figure out how to put a loop on it.
I took the short bamboo skewers (about 6" long) and glued stones, jewels, etc. onto the blunt end with E6000. I just had to make sure the stones had a hole large enough to slip onto the skewer. Voila, stilletos for a group of friends.
