A two-page article from Master Weaver No. 10 on pocket-type double weaves, where two cloth layers interpenetrate in blocks to form closed pockets. It explains the 8-frame, two-block draft in tabby, adding stitching frames to keep large pockets flat, and several warp and weft colour-exchange schemes that give mixed or gray effects. Five figures show drawdowns and colour-pattern diagrams. A short note on weaving terminology follows, recommending "locked weft" over "clasped wefts".
