Yeah, this method works really well. When I went to the NE Haunter's Gathering back in July, someone brought a Jack 'O Lantern with them that was made in this fashion. It looked totally awesome. He even made a stem for it out of blue insulation foam and glued it to the top of the head. The one at the gathering was quite large, I might add.Wouldn' it be easier to just cover balloons? Shape the outside like pumpkins. That would eliminate the cut and patch steps. You could go as large or small as you want in round or oblong. And it would be really cheap.
