Blackwork is a counted thread technique built up from the simplest embroidery stitch - a short straight stitch made over two or more threads. Combinations of these stitches make lines or geometric patterns which can be used to build up abstract designs or representational pictures. The technique came into vogue as a decoration on clothing in the early sixteenth century, and the author begins by tracing the development of blackwork from the earliest authentic records to the present day. The following chapters cover the practical aspects of blackwork. Any attractive or intriguing pattern can be used as the basis of a blackwork design, and the author considers a wide range of possibilities from natural sources, such as bark, leaves and frost, and from man-made sources including Moorish architecture, brick patterns and wrought iron work. A good design method is essential for a successful piece of work, and Margaret Pascoe explains the principles and the various methods which can be used - for example drawing, photography and paper collage. Subsequent chapters are devoted to materials (fabric, frames, threads and needles). making a sampler, making a panel, mounting and framing, blackwork on clothing, and mixed techniques.
