The Secret Garden

Metalsmithing with Shannon Sunderland (ages 11 and up) In Victorian times, the language of flowers was used as a means of communication. Certain flowers had secret meanings for the recipient, which allowed the sender to convey feelings that could not be easily communicated. Armed with floral dictionaries, Victorians often exchanged small “talking bouquets” or “tussie-mussies,” which could be worn or exchanged as a fashion accessory. Shannon will present a study of the historical and cultural meaning of flowers. Students will then choose their own flowers to make out of metal, resulting in a beautiful necklace that will be unique and personal. We will explore metalsmithing techniques including piercing, filing, texturing, stamping and patina application. No prior metalsmithing experience necessary. If you have a personal favorite flower, bring an example (drawing, online image, photo or actual flower) and we will stylize it in metal together. Price includes all materials. Space limited. $160

Saturday, tbd, 10:30am-1:30pm (adult and mature teens)
