April 6-8, 2018

Students will learn Kory’s NEWLY designed Three Step Fabrication Method® to simplify the steps in creating a Freestyle Flower Garden ® on glass  The class will discuss her strip cutting approach to breaking down the glass to patternize flowers. This is a wonderful opportunity to understand how to organize your mosaic from start to finish.

The three day workshop will be a combination of lecture/slideshow, discussion, Q&A, demos, and hands-on instruction.  We will focus on Glass on Glass (GOG) application, using the direct method to create a stimulating optical effect. The students will up-cycle a cupboard door into a beautiful stained glass mosaic sun-catcher. Students will learn Kory’sThree Step Fabrication Method® to effectively and efficiently construct a Free Form Flower Garden glass piece. Kory will demo several unique cuts she uses in her gardens, using three tools, nippers, a scoring tool, and running pliers.  Kory will demonstrate and discuss a specific nipping style /technique, Glass Shaving® to create a crisp clean edge, using only wheeled nippers. The class will explore how to create movement, using Kory’s signature cut, One-cut Sliver Cut®.  Additional topics covered include: committing to a design, selecting a color pallet, varying opacity, Randomization Method®, balance and composition, creating a one-of-a-kind designs, and incorporating found and unusual items. Kory will discuss grout bleed, adhesives, grout additives, and provide tips and tricks to grouting.  Mac glue will be provided. Students are encouraged to bring additional unique items such as broken jewelry, beads, and tesserae to embellish your mosaic.

There will be a grout demonstration  on Sunday. Students are welcome to grout if they have completed the project and glue has dried. If projects are not completed, or dried by 2 pm then a grout package will be available to take home for optional grouting.

Quick-Release Mosaic: Three Works in Two Days

May 3-4, 2018

kk1Build a cohesive series of three mosaics in three days! You’ll work small (7” x 5”), choosing one of several modern designs and then executing that design in three different ways (changing the andamento, the materials, the colors, etc.). On day one you’ll map the entire series to scale on paper, learning about composition and continuity (and more!). Then you’ll transfer your designs to your substrate, select your materials and begin to create, with one-on-one guidance as you go. On the afternoon of day three we’ll do a critique and toast your completed series. In this 3-day process you’ll learn to free yourself up, trust your instincts (there are myriad “right” decisions; pick any one!), stop overthinking choices (keep moving forward, stop futzing), avoid the paralysis of too many ideas/materials (set some constraints); produce a balanced, well-composed, and related series of works; and watch your design/technique develop and refine. And of course along the way you’ll be learning new ways to cut/set tesserae and work with thinset.

Cost: $385 + $15 supply fee for substrates, mortar, cups, stirrers, handouts, etc. (Students bring their own materials/tesserae and/or purchase from workshop stash.)

Kickassiette: Blowing the Lid Off of Crockery Mosaic

May 5 & 6, 2018


Picassiette* is the process of transforming crockery and found objects into mosaic. What makes crockery so tempting and ideal for mosaic is not only its availability, ease of cutting, and varied glazes, but its unique curvatures, bumps and protrusions that translate to gorgeous dimensionality in tesserae.

In this technique-rich, hands-on workshop, Kelley ramps picassiette up an innovative notch – to Kickassiette! – with her unusual methods of cutting/setting not only the flat surfaces of plates and other ceramicware, but the lips, feet, rims, handles, lids, spouts, and more, including the inner clay body. Students will learn cutting tools and techniques; setting in mortar to maximize sculptural/dimensional possibilities; building a cohesive color/material palette, and composing with crockery’s challenging curves and bumps.

*Thought to be derived from the French slang “piquer” (to steal) + “assiette” (plate).

Cost: $385 + $15 supply fee for substrates, mortar, cups, stirrers, handouts, etc. (Students bring their own materials/tesserae and/or purchase from workshop stash.)


Visual artist Kelley Knickerbocker left a 22-yr administrative career at the University of Washington in 2006 to found her studio (Rivenworks Mosaics, Seattle) and begin designing/ fabricating/installing mosaic artwork for public, commercial, residential and gallery environments. Kelley’s ruggedly dimensional mosaic artworks are a textural distillation of her fascination with contrast, material properties and the technical challenges of mosaic construction, and garnered her the 2015 Innovation in Contemporary Mosaic award from the American Society of Mosaic Artists.  Her work is widely collected and regularly exhibited in the US and abroad. In addition to her studio practice, Kelley travels extensively speaking, collaborating, and teaching in-depth workshops on mosaic style and technique.
