Procrastination aside, folding units for a new kusadama is always an adventure. This “parquetry” ball looks like it is made from strips of machined timbers. I decided on 3 colours, reasoning that I should be able to evenly spread the edges around the ball:

Due to the interconnections, the plan nearly worked, but the ball is lovely none the less. I really like the locking mechanism – the resultant ball is rigid and self-supporting.

I can imagine folding this in all the same colour paper (bi-colour), and may re-fold sometime. You can have a go for yourself, by following along to the youTube tutorial.
