From what I see, there is no way that lady gets 24 fat quarters from 1 can...she was really laying it on. Expensive in my mind is doing my stash like she did..it would cost a fortune! Each to his own. What I remember from home ec class was that a little goes a long way, anything else is waste. For stiffer fabrics we were taught to do it in 2 or 3 stages, ironing in between..maybe that has changed over the years. I don't use spray starch at all, so maybe I'm out of the loop...it just looks likes a ton of extra work...I only starch if I have a lot of bias cuts, and then I mix my own.
