Girl Scout craft: DIY Fire Starters for Camping - You begin with an empty egg carton, add old dryer lint, and cover in wax. You just let the wax dry, break them into 12 individual cups, and light the cardboard corner to start your fire.
First-rate fire starters: Pack sawdust into paper muffin cups or a cardboard egg carton. Melt old candles or paraffin, pour over the sawdust & allow to cool. Burn slow when lit but make great starters for a fireplace or campfire.
