Robert Lang said: "If one folded the masu without sharp folds at the four vertical edges, so that the sides were smoothly curved around the corners, then I *would* consider that to be a dry tension fold; the stresses would reside in the curved layers. But once you create sharp 90° folds at the four vertical edges, that relieves the stresses, hence no "dry tension," IMHO." Yes, agree. Then I believe the key concepts that would completely define this technique are - The lack of relieve of tension at some zone of the paper. - The lack of use of any tension relieving technique, wet or not. So the "dry" and the "tension" are defining points after all, even if some tension relieving techniques are not "wet", like metal foil. It is interesting to think about the curled kusudamas of Herman Van Goubengen and others, in which the 3D and the heavy curling are present, but the paper has taken the curled shape into "its memory" so there is no tension.
