Bound using the Coptic stitch, there are six signatures in this book. The cover is Lokta paper over binder's board.

Inside, I've used bark paper (also called Amate paper) from South America in four colors: white, blue, marble, and brown.

Mask #1 (top)  

Mask #2 (center)

Mask #3 (bottom)

The front edge design is from a vision serpent ring I sculpted.

I paired the blue and white bark paper for three of the signatures. Leaving the outer page of the signature long, I could make a flap over the inner page by folding the excess paper over.

For the other signatures, I paired up the marble and brown paper.
