All fabrics have the capacity to absorb, reflect, or transmit light to a greater or lesser degree based on the unique physical properties of their raw materials and construction. In this course students print and dye light-absorbing wool and light-reflective silk, exploring depth, shadow, luminosity, and transparency. While visual qualities of wool and silk are often dissimilar, both are protein-based fibers and, as such,respond best to acid dyes. Students learn the chemical processes of these dyes, refine the handling of color, investigate the design potential of each textile surface, and expand their printing and dyeing skills. The expressive qualities of printed silk and wool may find application in fashion, interiors, and fine art oriented work.
