Clematis Tessellation

This is a relatively simple tessellation which should be suitable even for beginners. Despite the simplicity, with a bit of shaping, it can look quite nice.

The pictures below show the precreasing and collapse of a 2×2 molecule tessellation, which requires an 8×8 square grid (4×4 for each molecule).

1a. Start with an 8×8 grid. Precrease as shown.

1b. If you want to make a clean fold, precrease only the lines shown here. This will be more difficult to precrease and collapse but will result in a fold without any unnecessary creases visible.

2. Actual precreased sheet.

3. Start collapsing the base (a sunk square twist).

4. One base completely collapsed.

5. All molecule bases collapsed. Align the movable flaps in such way that each molecule has a consistent twist direction.

6. Fold a rabbit ear through all layers on one triangular flap.

7. Open the layers in order to shape the petal.

8. Finished model, after shaping all petals.
