Spin to Weave is not simply a How-to-Spin book, but a How-to Spin-Exactly-What-You-Want book, featuring in-depth information on fiber properties, color choices and options, and lots of spun samples. Because weaving is a two-element technique (warp and weft) as opposed to a single element (as in knitting and crochet), there is a much greater variety and range of possible yarns that can be used, either together or separately. Spin to Weave focuses on the process of spinning for specific results, with variations that spinners can use to their advantage, a sampling of projects, and a gallery of projects by other spinners. The book begins with text, photos, and samples on how weaving can be affected by fiber choice, fiber preparation, twist insertion, twist direction, and twist amount. Author Sara Lamb spins single and plied yarns in several types of wools with different twists, and then uses these yarns in samples with several simple weave structures. Yarns will be finished in various ways, and the samples will be finished to produce truly custom effects. A short section of simple woven projects follows, demonstrating the fabrics in action, and also showing the effects of customized color treatments, including Sara’s signature warp-painting technique. A gallery of other weavers’ projects rounds out the book. Even slight variations from yarn to yarn can change woven fabric dramatically. Weavers who spin their own yarns have the ability to choose fiber type, method of twist insertion (woolen, worsted), twist amount and/or direction, finishing methods, and grist. All these factors are limited in commercial yarns, but accessible to the spinner, and offer a nuance in finished fabric otherwise impossible to achieve. Sara takes reader to the very beginnings of woven fabric--introducing the thought processes and concepts related to choosing fibers and how to spin them with the finished fabric in mind.
