(Doup) A construction of woven fabrics in which the resulting fabric is very sheer, yet durable. In this weave, two or more warp yarns are twisted around each other as they are interlaced with the filling yarns; thus securing a firm hold on the filling yarn and preventing them from slipping out of position. The yarns work in pairs; one is the standard warp yarn, the other is the skeleton or doup yarn. Also called the gauze weave. Leno weave fabrics are frequently used for window treatments, because their structure gives good durability with almost no yarn slippage, and permits the passage of light and air.

a weave in which the warp yarns are arranged in pairs with one twisted around the other between picks of feeling yarn as in marquisette. This type of weave gives firmness and strength to an open-weave fabric and prevents slippage and displacement of warp and filling yarns.

An open weave created by arranging warp yarns in pairs, and twisting them alternately in a right or left hand direction before inserting the filling yarn. Also called a doup weave - it naturally adds strength to open weaves and prevents yarns from shifting out of position.
