Great idea... modified. (Cheap, easy & HEALTHY dryer sheets.)
"WHAT YOU NEED:
1 Container with an airtight lid (grabbed out of my pantry) - No change
4 sponges cut in half ($1.00 for a 4pk at the dollar store) - Leave sponges whole, less likely to fall apart.
1 cup of your favorite fabric softener - Replace softener with white vinegar and fill to top of container.
2 cups water - Water is unnecessary, no need to dilute vinegar.
10 drops essential oil - my favorites are tea tree oil and peppermint oil mixed together
WHAT TO DO:
Mix the water and fabric softener into a plastic container. - Pour vinegar in the container and add essential oils..
Add the cut sponges so they can soak in the mixture. - Add sponges.
When ready to use, squeeze the excess liquid from 1 sponge and place into the dryer with your wet clothes. - No change from here on out.
Run the dryer cycle as normal. Once complete place the now dry sponge back into the container of liquid for use next time.
Clothes smell good, are soft and have no static just like the expensive non-reusable dryer sheets."
