Tent folding (Posted on 2004-12-30)

In folding an irregularly shaped tent, I managed to get the shape of a triangle, which was evenly thick. Unfortunately, the best way to fold a tent is in a rectangle that is evenly thick. How can I fold a triangle into a rectangle without making some parts of it thicker than others?

Take the corner with the largest angle and fold it to the opposite side with a fold parallel to that opposite side. Fold the other two corners to the same point. No matter what dimensions the triangle had, it is now a rectangle.
