1 Container with an airtight lid 4 sponges cut in half (from $1 store) 1 cup of your favorite fabric softener 2 cups water WHAT TO DO: Mix the water and fabric softener in plastic container. Add the cut sponges so they can soak in the mixture. When ready to use, squeeze the excess liquid from 1 sponge and place into the dryer with your wet clothes. Run the dryer cycle as normal. Once complete place the now dry sponge back into the container of liquid for use next time.
Not that I use dryer sheets but… "Felted wool dryer balls are an easy to make, non-toxic alternative to fabric softener and dryer sheets. Throw of these in the dryer with your laundry and you will never go back to dryer sheets again."
