I have a suggestion that we used at the camp I work:

Vet wrap! Our camp had horses and we realized the same elastic tape used on the horses was extremely useful in the medical center! The tape only sticks to itself and it's much cheaper than ace style bandages. It comes in fun camp colors (we used pink, green, orange, red, blue, purple, etc) and we used it for sprains and with gauze to cover large wounds.

Yep... you might look for it branded as Coflex or Coban, although I don't know how the cost compares to what you are using now.

We were using 3M but it costs about the same as coflex in bulk.
