Dryer lint is a great fire starter. I take it and shove it in the leftover papertowel and toilet roll holders and cardboard egg cartons that don't get back to the farms. The long rolls I place a used papertowel in the ends. With the egg cartons I melt broken candles or just to short to use candles I drip the candle wax over the lint, when I use them to burn leaves or just have a small backyard fire I cut the eggs one into 12 pieces. They start a fire really nice and my grandson likes to stuff the lint into the holders.
