Origami giraffes are difficult because of neck and legs and the amount of paper that needs to be dedicated to in order to achieve such proportions. I made a first draft of the head, attempted to graft a body on, then modified the head after several revisions of the body. Overall, I think it is one of the more polished models overall and I am happy with the result.
Made from one sheet of square, uncut printer paper (for each girafficorn)
