Step 2: Assembly
Take a single hook, and heat the straight end using the lighter. If you have a blowtorch style lighter, that's all the better. You want the metal to heat up pretty well.
Once you are satisfied with the temperature of the hook (too long and you'll start feeling the heat spreading to the area you're holding, maybe I should recommend gloves), you'll insert the heated end into the bottom of the crayon. The faster you do this, the better. You'll be less likely to split the crayon, and the wax will yield nicely. Then it will hardden around the hook. The bond is sturdy enough for the crayon to remain on the end without it slipping off while hung.
