I am looking at Tomoko Fuse's book on Floral Origami Globes and made the structure made up of twelve flat units.
This seemed pretty straightforward and I got a nice little shapr out of it.
I decided to go for a more complicated project so - keeping with the twelve unit structure I went for the Centre Gathering/Type III 12 unit structure.
I have made all the base units and thought I would fit it together the same as the flat 12 unit structure but it's more complicated than that

Should I make four 3 unit structures and then fit them together or make one 3 unit structure and add the other base-units to it to build it up - like I did with the 12 unit flat structure?
Grateful for any advice.
