Wear, Design And Enjoy Clothing, Seung Baik

Theses

Many artists choose to combine metal and textile to execute their works. Metal elements are sewn, woven, and crocheted into garments, sculpture, ornament, or decoration because it fastens directly to fabric to make a richly creative and decorative effect. Also, the qualities of metal provide structural stiffness, weight, and light (reflection) to the fabric. I explored different ways of integrating metal and fiber into the fabric of woven yarn structures. "Using textile techniques in metal does not constitute a movement or a style."1 However, treating metal like fiber is an intriguing concept with flexible possibilities for the two different materials.
