Book excerpt: In Shadowfolds, Jeff Rutzky, himself an accomplished and passionate origamist, and Palmer offer detailed and fascinating information about the technique and its origins in both Moorish tile and classic Japanese origami. Palmer first encountered the elaborate mosaics of the Alhambra and became intrigued with learning to translate these patterns into folded paper. He turned for inspiration to the work of Japanese origami masters Tomoko Fuse, Jun Maekawa, Toshikazu Kawasaki and Shuzo Fujimoto, as well as to the great American origami artists Robert Lang and Peter Engel. The transition to working in cloth followed. The flexible property of cloth allows pleats to be folded to augment and give a dimensionality not present in a flat surface; and the translucent quality adds a unique intricacy to the geometric patterns. When lines in a pattern are folded as pleats, the resulting shapes formed by the pleats become part of the artistic expression of the material. The possibilities for using Shadowfolds in design are limitless. Some applications take advantage of light shining through the fabric, others show the richness of the folds that have a depth all their own. In addition to explaining the three very simple steps of the technique, the authors show how even novice folders can create breathtaking works of textile art, as well as fashion-forward clothes, accessories and home furnishings incorporating these three-dimensional embellishments. They also include a section of patterns, and fabric and craft resources.
