Paper: 15cm square of Kraft paper
Finished model: 9cm length, 2.5cm height, 3cm width

Today I decided to try making tissue foil. Some spray glue, foil, and red and green tissue later I finished my first attempt. Not perfect, but good enough to check what it was like to fold a model out of it. So I searched for a simple duo-colour flower, and this is the result.

Paper: 27cm square of tissue foil
Finished model: 13.5cm x 13.5cm
flower: 8.5cm diameter
leaves: 6.5cm length, 4.5cm width

With backlighting, you can see that towards the middle of the model more and more layers of paper lie on top of each other.

Folded on 16 October 2008
Paper: 20cm square of transparent paper
Finished model: 10cm x 10cm
