Onebyone, that's good to know as I've looked high and low for Vodka made with potatoes thinking it's because of the starch. I used to add Vodka to my starch mixture but didn't see much difference using it so stopped.
I also from time to time, will put some of my starch mixture into a spray bottle to use while pressing but since I make such a stiff starch mixture, I haven't had to do that. Still there are some fabrics that will fray no matter what you do to try to stop it from fraying.
