Step 9: Repairs
If you accidentally cut a piece off that wasn't supposed to be cut, line the piece back up and push a few tooth picks at different angles into the cut edges to hold the piece in place.
If the section that was cut is too small for a toothpick, use individual staples instead. Don't staple directly onto the pumpkin, just break them off one at a time and push them in by hand.
For very serious repairs, you can even cut a whole new section of pumpkin using the pattern and graft it onto the pumpkin - though this is extremely difficult to do.
