Book

Paper: 6 sheets of kami, 5.8cm by 2.9cm (approx. 2 1/4in by 1 1/8 in)
Model: star with a diameter of 5.5cm (2 1/8in) and a depth of 2.5cm (1in)

Yesterday I had the idea of making a 3D star from the Sparaxis units, inspired by another model presented in Katja's book. I like it! The picture shows front and reverse of the model, the different colors were achieved with patterned paper.

Paper: 30 sheets of kami, 5.8cm by 2.9cm (approx. 2 1/4in by 1 1/8 in)

I've long loved Katja's fantastic website, so I was super excited to hear about her book. Here's my first fold from it! It took a while, but I absolutely love it.
