Yes, you read it right: DRYER LINT. Believe it or not, there are some practical uses for the grey-ish white-ish puffy fluff that you clean from your lint trap.
Kindling. Dryer lint has long been known in the Boy Scouts culture as an excellent fire starter.* Check out these simple instructions and take some lint along on your next camping trip.
Nesting material. Pet stores sell this stuff, but you can find it for free in your dryer! Works well for hamsters, guinea pigs, rabbits, rats and other similar creatures.
Compost material. Lint from organic material (cotton, wool) can be added to your compost pile.
Crafts. Really, truly — you can make clay, papier mache and paper from lint. Here are instructions for all three.
*Because dryer lint is highly flammable, you should clean your lint trap as often as possible (after every load is best). This will prevent build up that can start a fire and allow your dryer work more efficiently. And since dryer lint is so flammable, it should not be used as stuffing for toys or pillows.
