Paperback. Zustand: New. Print on Demand. This book spans a period during which the invention of the lace machine brought about great changes to the lace industry. This book examines the evolution of bobbin-net lace, from its origins to its dominance during the nineteenth century, and reveals how a series of technological changes transformed British lace from a luxury product to one that was accessible to all. An in-depth analysis of the many different systems of bobbin-net machines is presented alongside a fascinating account of the impact that lace had on the lives of those involved in its production. This book not only traces the history of lace but also explores the ideas surrounding the practice. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Bestandsnummer des Verkäufers 9780282328542_0
