My next decision, drawing and painting is really a series of decision making good and, sometimes, bad, is to sketch in the various folds and twists of the headdress.
Drapery can be distilled into seven types of folds, each with their own distinct characteristics and logic. These seven folds are the pipe fold, the two-point fold, the zig zag fold, the half-lock fold, the spiral fold, the drop fold, and the inert fold. The headress is comprised of all the fold types except for the drop and inert folds.
An understanding of the characteristics of drapery goes a long way towards drawing and painting believable clothing. If you find yourself making up folds as you draw then you are significantly weakening your work.
