Someone just posted to turn fabric so back is showing and spray to eliminate chance of flakes on the front (flakes wash out or can be brushed away but are annoying). Also, warm fabric with iron, then spray. makes the starch absorb better. I have also read to spray, wait for starch to dry a bit, then iron to prevent flakes. Also read that if you use aerosol, sometimes it comes out in fits and spurts but that the nonaerosol is easier to control and sprays more evenly.
