I've been quiet for awhile and this is why. I have spent the last 8 months (almost) working in my spare time to create my largest origami portrait mosaic. The entire piece measures 87x58cm and is composed of 6,144 pieces of paper. Each piece of paper measured 2.5cm square. All in all I've estimated the total time spent on this to be about 220 hours based on prep work, average folding and assembly time.
