This morning I was laid awake thinking about this and how it looks more egg shaped than spherical. I did look at exercise balls (which I migh revisit in future) but then it hit me that I could make a cage, out of string, for the balloon to inflate inside.
It should hopefully constrain the balloon enough to keep egg shaped and might even contribute to a more pumpkin shape! I'll give it a go on Tuesday eve.
