Before you start carving, it would be wise to cover the surface where you will be working with one or more sheets of newspaper. This will make it easier for you to clean up after you have carved the Jack-O-Lantern.
Use a medium knife to cut away the stem of the pumpkin you are using to make the Jack-O-Lantern. Be sure to cut at an angle of about 45 degrees to keep the stem from falling into the pumpkin. Moreover, the resulting hole at the top of the pumpkin should be large enough for your hand to easily fit through.
Remove the pumpkin pulp into a bowl with the help of a medium serving spoon. Save the pulp for later use because you can roast the pumpkin seed and eat them.
Sketch the desired design of the Jack-O-Lantern onto the pumpkin shell. Use a dry erase marker for this purpose.
Now it comes to the actual carving part. Use a small knife to cut the pumpkin shell perpendicularly along the design that you drew earlier. Discard the pieces that become loose and after you have carved the pumpkin, wipe clean the dry eraser markings that still remain.
Carefully place a candle inside the pumpkin and light it with a lighter. Your Jack-O-Lantern is now ready. Display it at your desired location.
