I get the concentrated gallon bottle of Sta-Flo starch, dilute it normally 50/50, put in a spray bottle and spray my fabrics. This way it costs about 1/10th the amount of the commercial starch, and if I want it stiffer, then I change the dilution amount. I spray on the right side of my fabric, let it "soak" a minimum of 2 hours, then air dry or put in the dryer for a few minutes, take out, mist with water, iron.
