It’s been asked if I’ve done other Blenko shapes for iris folding. I have not. I picked the water bottle because it is such a distinctive shape, and the body of the bottle is basically a square. This allowed me to use a standard template for a square opening. Any other shape I would have to create a specific layout pattern, and I just don’t have time. However, as a consolation prize, I send you my tangerine water bottle card.
