Wet Folding & Moisture absorptionOrigami & Folding
Estimate optimal water moisture weight to apply based on paper thickness, weight (GSM), and wood fiber content for perfect wet folding curves.
Origami is the intersection of mathematical geometry and material engineering. Optimal folds are highly dependent on fiber lengths and wood grain direction.
Using a super-fine water mist atomizer.
Ideal wet folding window. The paper becomes leather-like. Holds creases perfectly while allowing gentle modeling and soft contours.
