hey, i just made a sample football cake, and had issues with leveling the uneven side, that's with only needing half a ball, i need to make a life size ball, how would i get that to sit up like a real football?

The bottom is going to have to be a little flat for it the sit. I recently did one and carved from the tips down to get the rounded bottom. Just do a little at a time and it will start coming into shape.
