That part of a fold which is farthest from the ends where it is
confined will fall most nearly in its natural form.
Every thing by nature tends to remain at rest. Drapery, being of
equal density and thickness on its wrong side and on its right, has
a tendency to lie flat; therefore when you give it a fold or plait
forcing it out of its flatness note well the result of the
constraint in the part where it is most confined; and the part which
is farthest from this constraint you will see relapses most into the
natural state; that is to say lies free and flowing.
