The drapery Vilde roses by textile artist Frida Hansen (1855-1931) was displayed at the World Exhibition in Paris in 1900. At the exhibition Hansen won the gold medal for her artistry and work with the company Det norske Billevæveri that she started with Randi Blehr. The characteristics of Hansen's work is her way of leaving parts of the warp visible and thus allow light through the fabric, a technique which she called transparent technique and patented in 1897. The curtain is woven a wool tapestry with fringe at both ends. Hard twisted blue-gray wool has been used for the warp, while looser spun wool yarn in white, green, gray, pink and yellow has been used for the elements. Large portions of the warp is left unwoven.
