Microfolding and Corrugation

Microfolding can also be called corrugation. The wavy undulations add strength to thin metal, making it possible to create large, yet light and sturdy, jewelry. This process offers endless possibilities for creativity through texturing and forming.

In this 5-day intensive, a wide variety of techniques and textural possibilities will be demonstrated, including fanfolds, ribbon forms, smocking, confirming and pleating, fold forming, and making microfolded beads. Each demonstration will be followed by work time. Though process and technique are emphasized in this class, rather than being project-oriented, you may choose to bring silver for making finished jewelry, once you’ve mastered the techniques in base metal! Each student can expect to make lots of samples and at least one piece of finished jewelry.

Whether using hammers and stakes, or hydraulic press tools, Cynthia's sculptural jewelry and hollowware shows her focus on exploring the fluidity with which metal can be moved, formed, and joined.

Cynthia Eid co-authored the book Creative Metal Forming, with Betty Helen Longhi, published in 2013 by Tim McCreight's Brynmorgen Press. In his foreword for the book, Michael Good says the authors "have succeeded in assembling the first comprehensive textbook on synclastic and anticlastic forming." (More about the book available at www.creativemetalforming.com.)  

Cynthia and Betty developed a set of anticlastic stakes, and Eid also works with Knew Concepts and Bonny Doon to help make tools for jewelers and metalsmiths. Lee Marshall has dubbed Cynthia Eid "Godmother of the Knew Concept Saws" since it was her idea for him to produce these saws for jewelers.

Excited about working in sterling silver without the problem of firescale, Cynthia has been working with Argentium Silver since 1999. After meeting Peter Johns (the inventor of Argentium Silver) in 2003, Eid has participated in AS's development. Argentium International, Ltd recognizes her as a Pioneer.

Cynthia Eid's metalwork has won awards for creativity and design, been featured in many publications, and been exhibited internationally. With a BS in Art Education and MFA in Jewelry, Design, and Silversmithing, she has previously worked as a bench jeweler for fine goldsmiths, a model-maker in a gold jewelry factory, and on private commissions. Her work is in museums in the US and UK. Currently an independent metalsmith and educator, she teaches weekly classes at Metalwerx in Massachusetts, and workshops and short courses in the US, Canada, Europe, and Australia.
