Super easy to make and the best of it they stay dry and still work if you get wet!
Good for outdoors, chiminea, or the fireplace in the house because they burn clean.
Dryer lint (I use anything. No "just cotton" lint and all of that jazz. Nylon, cotton, Rottweiler hair. It all burns)
Cardboard egg cartons
Paraffin wax (I use Gulf wax) All of those Christmas or Hanukah candles they blow out for cents on the $$ also work well
Pot you don't mind wrecking but I have cleaned them out (Of course I am obliged to tell you you need a double boiler)
