The size and shape of your design will determine whether you need a tall narrower pumpkin or a round one.
Decide your design in advance and choose your pumpkin accordingly. Choose a pumpkin that is smooth as possible, and free of scratches, dents or gouges, unless you plan to incorporate them into your finished design.
You can make the transferred dots of your pattern easier to see by rubbing flour into them. The flour will fill the holes and turn them white.
To make sharp corners, always remove the saw completely and re-insert it at a different angle.
To remove cut pieces, push them out from the inside with your finger or a poker. To make removing large pieces easier, and to avoid damage to your design, cut them into smaller chunks before trying to remove them.
