Take a package of soft cloths (e.g., generic brand of J-Cloth) and cut them in half. Soak in fabric softener, wring out well, and hang dry. When ready to put a load of clothes in the dryer, slip a dried softener sheet in. These can be used a few times over and then you can start the soaking process over again. The sheets last forever and you'll never need to buy fabric softener sheets again.

Reusing wash cloths soaked in fabric softener, wrung and dried, you can make your own dryer sheets. This is a page about easy reusable dryer softener sheets.
