"Modern Tweed" by GGH is a fine tweed yarn available in earth tone hues. This boucle fiber is made up of 48% wool, 23% acrylic, 18% nylon, 10% alpaca and 1% elastan. The elastan (elastic) is just enough for the knit to hold its shape in oversized, light weight coats while the alpaca insures warmth. "Modern Tweed" is primarily used for oversized jackets, coats, sweaters and wraps.
