One year is necessary to build a falla.
The artist begins to build a model with clay or plaster.
Then he builds each subject and personage of the falla with clay to create the mould.
Finally he builds the definitive elements with pasteboard.
Once the pasteboard is dry and removed from the mould, the pieces are assembled, painted and placed on the wood framework which will support the falla.
The sculptor modeller, the carpenter engineer and the humorist work together for this realization.
