It's easy to make upcycled firestarters to use to get your wood-burning stove or fireplace roaring in the fall and winter months. Save cardboard egg cartons, old candles and dryer lint. Tear large pieces of dryer lint and place it inside each egg carton compartment. Then melt the old candle in a heat-resistant glass container over simmering water. Pour the melted wax into each compartment, covering the dryer lint. Allow it to cool. To use your firestarter, just tear one compartment and light the cardboard in the fireplace. It'll burn slowly and evenly and allow your fire to "catch" and get going.
