If you end up having to buy extra cords or stoles, you could probably find girls in your chapter who may want to buy the extra from you...and of course, there is always E-bay! As long as there isn't a graduation date on the sashes themselves, your sisters may want to get some for their graduations even if it isn't at the same time as your own. Also, and this is just a thought, if you could talk your chapter execs into buying them, they could be given as gifts to sisters in the future who are in need of a present or pick-me-up
