Every fold has a point of origin. In a previous lesson I discussed how a fold originates as it leaves the surface of the form underlying it. This point of origin is also a point of tension. Our first fold is characterized by having only one point of origin and is referred to as a “pipe” fold, since the cross section of the fold resembles a pipe.
The drawing below is a diagram of the pipe fold.
In the drawing below, each of the folds starts at the waist, having only one point of origin, and falls freely, creating the round pipe configuration.
Notice how these standing figures below seem to be in motion. The sense of movement is achieved by having the drapery flow rather than copying it hanging straight down as in the original posed model.
