A collection of sixteen-harness point twill patterns compiled by Irene K. Wood from the weaving notebooks of Fred A. Pennington of Des Moines, Iowa. It opens with a short history of these damask-like twills and a biographical sketch of Pennington, then explains the common threading and treadling, with differences in design coming entirely from the tie-up. Most of the book consists of photographs of woven swatches (20/2 mercerized cotton, 36 epi) paired with drawdown and tie-up grids. A comparison section adapts selected patterns to twenty, twelve and eight harnesses, and a closing section shows step by step how to design your own diamond, star, circle and square point twills.
