You could try it and see. My thought is that Elmer's probably has emulsifiers :?: and other ingredients that thicken the starch and help it flow. Homemade starch will probably have more water in it and therefore taking longer under the iron to dry. It would be interesting to come up with a home recipe that works, though.
