I use spay starch, either can or sta flo mix my own, in the washer then transfer to the dryer. Dry until dry, then iron with steam. I iron the devil out of it. If it is going to shrink or get all wonky I want it done before I cut it. Sta Flo is more economical. My grandmother would use mix your own starch, powder I believe, and the after the clothes were dry, starch them, roll up and put in fridge over night. Then sprinkle with water and iron the next day. This was how all cotton clothes were starched and ironed. She used pant stretchers on my grandpa's work pants. Even workmen wore heavy starched and ironed work clothes, overalls, and flannel shirts too. They kept the dirt from grinding in the clothes for less work removing it. Thus the old list of Wash Day and Iron Day.
