The sequence for deriving the Pizzelle is explained below:


A picture of a pewter casting of Fan Coral is the starting point:
Then it is mirrored using a photo editor:

The Fan Coral is rotated by 30 degrees:
Then a segment is cut off:
The segment is mirrored:

The result is then rotated by 30 degrees:
Then cut at horizontal axiz:
The resulting segment is mirrored:

The result is then rotated by 30 degrees:
Then cut at the verital axix
The resulting segment is mirrored:
This is the final design:
