Fossil

Folding this stylized Fossil will exercise your squash folding skills. Even with all the color changed patterns, there are no wrap around folds. This model has an "intermediate" level designation. Diagrams for this can be found in the book Prehistoric Origami:

A single square of larger kami is recommended (10"/25cm). With more practice you can use smaller sheets.
