This is the original leaf design I produced a couple of weeks ago, consisting of only 2 main parts:
Since then I have worked on a design consisting of 3 leaf repetitions, on a smaller scale for experimentation:
This is what the form looked like when folded together and attached at the base:
I then repeated the form and attached 4 together to produce a floral effect.
This has proven rather successful, so I shall look into different scales and also add more repetitions to produce a more spherical shape.
