Special Guests

PCOC 2019 is proud to announce the following special guests:

João Charrua

João Charrua was born and brought up in a small town in southern Portugal. At an early age he developed a taste for the arts, especially drawing, studied arts at high school and years later he graduated in architecture. During the initial years of his career he trained and worked with a number of senior architects at several studios. He now has his own studio. It was out of mere curiosity that João Charrua first took up origami, which developed into an absorbing hobby and later a serious undertaking. He sees origami as a complementary activity to his profession, essentially as a means whereby he can freely express his creativity. He is passionate about illustration and everything to do with fantasy and the fantastic from which he draws most of the inspiration for his works. Don't be surprised if you catch him daydreaming - it's just his prolific imagination at work. In his free time, he enjoys the small pleasures of life, drawing and playing with his children.

Here are two great articles about João and his designs:

The Origami Always Succeed (OAS) is a group of four designers from Spain that like to keep the folding atmosphere fun and ever-changing with new ideas and challenges for each other and everyone they meet. They are very social and love to share their enjoyment of paperfolding with folders and non-folders alike.

OAS forgoes rules, but some trends have evolved during their journey together. They hold weekly folding challenges, value complete failure as a learning tool, have a low tolerance for rules, and they enjoy social interactions with everyone, which is why they hold their meetings in bars.

They’re a very fun group of designers, teachers, and friends.

Goran Konjevod



Most of the folds I've ever made have been pleats. I tend to fold sequences of pleats that intersect and interleave to create tension that then forces the paper into a three-dimensional form. This pleat tessellation technique was discovered by Paul Jackson. Sometimes I sculpt the pleated sheet after folding. In addition to folding paper, I've also folded sheet metal and various meshes, as well as used folded pieces as patterns to make metal castings.

Sok Song



Sok Song’s passion for folding paper has bloomed from a hobby he taught himself from books during his childhood to an award winning origami design business called Creased, Inc.
