This is the easiest, cheapest homemade beauty product I have ever tried. I didn't even have to buy anything to get started -- everything I needed was already on hand! All it takes is a jar with a lid, a cotton ball, a box of cornstarch, and some perfume. That's it! I love the result, too.
How easy is it? Just spray the cotton ball until saturated. I think I did about 40 sprays. Put the cotton ball in the jar and pour cornstarch on top, making sure to leave some empty space. Screw on the lid and shake well. Let sit, shaking again a couple of times a day for a couple of days. This is not an exact science, as you can tell. Mine smelled good after the first day. (I got impatient.)
Now you have inexpensive bath powder to go with whatever perfume you wish and it has no added chemicals. How cool is that? Y'all need to try this for summer.
