I never use the aerosol spray. I buy Niagara liquid starch at the grocery and mix it with water in a spray bottle. You can control the amount of stiffness this way and also find no problem with the spraying. Works really well. Thanks for the info bearisgray....my Mom did this but I did not remember the procedure. Would probably work well for starching 1/2 yards before cutting. I starch a lot before cutting my 2.5" strips
