Two book reviews from the Bulletin of the Needle and Bobbin Club (1938). The first covers A. G. I. Christie's folio volume on English medieval embroidery (Opus Anglicanum), 10th to 14th centuries, with its descriptive catalogue and plates. The second reviews Reath and Sachs's Persian Textiles and Their Technique (Yale, 1937), covering Persian silk weaves from the Sasanian to Safavid periods: compound twill, compound cloth, double cloth and compound satin. Illustrations include a vestment detail, a drawing of a figure, a diagram of plain compound twill structure, and a Sasanian fragment with its reverse showing floated pattern wefts.
