You can use a couple different things for a treadle belt until you get one. A pair of panty hose (legs only) stretched and tied will sometimes work. If they will run a fan belt in a car... You can also use clear aquarium tubing 1/4 inch diameter and a nylon connector that can be bought in the plumbing dept at lowe's. This one I know for a fact works because I've seen it done. You'll need 6 feet of hose. trim it to fit.
