I don't spray starch anymore but dip, hang to dry and then press before cutting. I destroyed my ironing board cover spraying starch and pressing on it. The starch would eventually turn brown and then transfer onto my fabrics later on. I also use the vodka/sta-flo recipe for my starch. I pour it into a dishpan I have down here in my basement sewing room as I had a sink area added to it when I 1st moved here. Has come in handy many times for cleaning up paint brushes, etc. I also installed a large dowel rod above the sink to hang the fabrics as the dry on skirt hangers. Then when dry I take them to the pressing area and press them all flat. Any starch leftover goes back into a gallon jug and then into the fridge so it doesn't go bad on me. Also by dipping I seem to get a more even coating of starch than with spraying plus much more stiffer so less stretching on bias edges.
