Thought I'd share a tip from my friend Susan:
To save on dryer sheets, cut a sponge in half. Fill a container with one bottle of fabric softener and the same bottle full of water. When drying clothes, dip the sponge in the fabric softener solution, wring out, and toss in the dryer.
I have also recently discovered Angora Fabric Softener Concentrate at our local Fleet Farm Store. It is two small plastic packets of concentrate in a small flat box - I think it was around $2 and makes a gallon of fabric softener.
