Make your own spray starch. Here’s how:
Ingredients: 1 heaping tablespoon of corn starch 1 pint distilled water Consider adding a few fresh smelling herbs. This is only if you have fresh lavender or rosemary sprigs laying around and you like an additional scent. Otherwise, your spray starch should be perfect with just distilled water and cornstarch. Combine the cornstarch and water in a bowl, and stir until the cornstarch is completely dissolved. (The mixture will be milky in color) Add herbs for fragrance, if desired. Then, transfer to a spray bottle, and use. For best results, shake before each use. Commerical-produced spray starch usually contains formaldehyde. Starching clothes actually makes them last longer because dirt and perspiration sticks to the starch and not to the fabric.
