I formed this hemispheric yesterday and took pictures today. I made the hemispheric wiring part bigger instead of just one string.
One string was the simple idea, whenever it's possible to make anything in a simple way and style. I choose "simple".
If one string isn't enough to create a good enough craft, then, I add something to cover the weakness. That's the way I go along. Simplicity is the starter for me. The benefit is the clear mind about what and how crafts are.
