I have been using homemade spray starch for about 2 years now. Just add about a tablespoon at a time and try it on your fabric until you get it as stiff as you like. Also add a tablespoon of lemon juice, the juice keeps the starch fresh. I keep two bottles by my ironing board, one with light starch, one with heavy, and always shake it up very well before using. Hope this helps. You can use bottled lemon juice! MAWLUV
