I sometimes switch hands. I have the spray starch in a can and it's a little tiring. I usually do a quick sweeping spray. Then fold the fabric, press with my hands then open it up again. Lay it aside to set just a little. As far as spray bottles. I find one I like then go back and get a couple more. I dilute Sta-Flo and put it into a spray bottle. I don't saturate just dampen. Folding, rolling and letting set works for me. I clean my spray bottles with a couple drops of dish soap and hot water also after using. I only use 1-2 ounces of Sta-Flo in a 32 ounce bottle if that much. I don't like my fabric stiff as a board just enough for some body.
