Chevron Corrugation (UUDD-DDUU variant)
Another variant of my Chevron Corrugation (see more variants).
Since each chevron in the original Chevron Corrugation can be made to point up or down, I devised the schema of using combinations of the letters U and D to describe the layout of each particular variant.
Folded from thick laid paper with an interesting texture. However, this paper was quite soft which made folding and collapsing a geometric model with sharp folds like this difficult.
