Appearance
Chap. CXLVI.—How the Folds in Draperies ought to be made.
Draperies are not to be encumbered with many folds: on the contrary, there ought to be some only where they are held up with the hands or arms of the figures, and the rest left to fall with natural simplicity. They ought to be studied from Nature; that is to say, if a woollen cloth be intended, the folds ought to be drawn after such cloth; if it be of silk, or thin stuff, or else very thick for labourers, let it be distinguished by the nature of the folds. But never copy them, as some do, after models dressed in paper, or thin leather, for it greatly misleads.
