Q: "Are they each from a single piece of paper?"
A: Yes -- by far the most frequently asked question, and the easiest one to answer (I wish they all were simple yes/no questions). But it is usually followed up with "...because some of them look like they're woven..." which is not actually a question, but an observation, and an implied invitation for me to elaborate on the masks' construction. So I elaborate. It's a technique that is both structural and ornamental. Parallel folds make pleats that open up to form the convexities of the face and intersect with each other around the face. Where they intersect, twist folds are formed on the back of the piece which help to keep the pleats closed. The pleats get pretty tightly packed together, and where they run parallel to each other, the space between them looks like an individual strip of paper from the front. Where twist folds occur on the back, it appears that the "strips" of paper are crossing under and over one another.
