Tulle is an open-construction fabric made using three kinds of yarns. In the following image (green) warp yarns running with the selvedge are looped by (blue) warp yarns that run diagonally. At the same time another set of (purple) weft yarns loop the warp yarns and cross the opposite blue weft yarns. A Hexagonal design is produced by (warp) yarns and the two kinds of (weft – filling) yarns running diagonally. The regular even tension given to the yarns produces a firm, stiff netting called tulle. When fabric is relaxed, a hexagonal shape is evident. The fabric is starched to help it hold it design and produces a wiry, crisp hand. Tulle was first made as a foundation of laces in 1806 when John Heathcoat of Nottingham, United Kingdom ( see Lace post ) was trying to adapt his machine for lace production. Tulle netting is still the foundation of many laces. Tulle is still produced in Heathcoat’s Bobbinette machines which produces the highest quality of tulle. It
