Making homemade ironing starch is a great way to save money, reduce waste, and keep aerosol cans out of your home. I do not need to starch clothes very often (I originally wrote this when Mark had to wear dress shirts for work), but my sister, who sews a lot more then me, says starched fabric is easier to work with while sewing.
1 heaping tbsp of corn starch
1 cup water
1 spray bottle
Heat water until it is very warm. This makes it easier for the corn starch to dissolve.
Carefully pour into the spray bottle.
Shake the bottle. Spray sparingly on fabric and iron as usual.
