I was playing with the idea of some wrist bands today, they use just three balloons except for the ninja turtle which is only two.
All are prototypes so would probably be tweaked a little but possibly OK for the real world.
The second Elsa has no neck bubble and I was trying different colour combinations.

Slightly different ducks, I think I prefer version two.

A few more,

and then all together,

Nice Idea Graham, the second Elsa and Turtle stand out for me anyway

I made a few more today, I prefer the second frog.

I think the lady bug would be better with black feet and antenna so more or less what Rhian showed at the Leeds day.
Changed the butterfly a little, still only using three balloons to make them.

The owl looks like it needs a little tweaking.
