Best Press is sizing - not starch. I use Magic Sizing in the green can and it works great. I don't use starch because I live in south Florida and starch is a food source for critters. And we have enough problems keeping critters out without ringing the dinner bell!! LOL!! Sizing is not a food source so I don't worry about using it and leaving it in the fabric. But the only place I can find it is Winn-Dixie. Everyone else only has the blue can and not as good. You can get your fabric really stiff with repeated sprayings and ironing in between. My 2 cents worth.
