The process is based in heliography, printing using the power of the sun. Once dyed, pieces are laid out with leaves and stencils and left to dry in the sunlight.
Leaves and stencils provide the foundation for all Pualoa Company pieces.
Once a week, Bozo heads into the mountains on the windward side of O'ahu to gather leaves to use on his pieces. Every varietal has a particular use in a pattern and reacts differently to the sunlight.
Since the art form is contingent on the continual availability of these plants, care is taken to ensure that no one location is over-harvested.
The dye used is a non-toxic dye from France that is reactive to sunlight. A piece is dip-dyed or sprayed before being placed flat in the sun.
Leaves and stencils are then applied to each piece to create a pattern. Once dried by the sunlight, any exposed piece of cloth will keep a strong color, while shaded areas will lighten.
The finished product is greatly affected by the weather and quality of the sunlight on any given day. A hot and sunny day will create strong outlines and vivid color on the cloth, while an overcast day may give a softer and more subtle print.
