I was trying to remember a Ball design David Crofts showed at one of the balloon days.
It started with 4 bubbles as per the first two balls. I than made 5 bubbles to start so it was slightly more rounded.
The Purple ball is 3 finger bubbles, the Yellow is 4 finger bubbles and
the five sided Goldenrod I went back to 3 finger bubbles.

I then made a larger ball with three double triangles as the starting point.
It did not end up symetrical.

I filled in the sides of the larger ball and then as it was not symmetrical made the ball that is a few years old now.
This was from way back at one of The Millennium Jam conventions, which is symmetrical.

I made the ball again a different way and think this is more usable for the real world now.
I used to struggle before in remembering how it went together.
