Something new in needlework: a triangular stitch, basis of a hexagon, basis of a thousand and one patterns. . . ""Standing by itself, the equilateral triangle looks a proper, stolid, upright figure. Surround it with neighbors of identical size and shape, start coloring, and watch the flummery start. Designs hop in and out of perspective; two-dimensional surfaces mysteriously deepen into three. . ."" and the pattern takes on perpetual animation. Excellent color plates, simple, precise instructions, unusual results.
