Weaver's Craft Issue 13: Four-Shaft Twill Sampler

Each issue provides in-depth information on a weaving-related topic, as well as several projects.

From the publisher's website:

Compare a woven cloth to the black and white squares of a graphed drawdown and you'll quickly realize the shortcomings of the graphed representation. As absolutely indispensable as drawdowns are, their rigid rows of squares are mocked by the yarns of the cloth, which nestle together according to their own rules. Explore the possibilities of four-shaft straight twill threadings by choosing from sixty-two treadling variations (you can design even more yourself), and weave a reference sampler or several Sampler Hand Towels, Guest Towels, and Cord Weave Scarf.
