Combining two designs can work. Here is a combination of a stapled pumpkin and a drowning pumpkin. The carver called it the pickled punk pumpkin.
Lots of people take alternative approaches to the drowning pumpkin. Working with a clear bag is harder than most people want to handle. Using a big clear bucket is a good solution, but it won't accomodate a large pumpkin.
When I am not carving pumpkins, I run a bulletproof vest company. BulletSafe Bulletproof Vests are the value leader in body armor. We are very popular with people like armored car operators and ATM repairmen.
