Crossover (Clay/Wood) • Adult • Animal Masks • MON (Mar. 2 - April 20) • $355 • MAIN
with Margaret Josey-Parker
Come explore the intriguing world of mixed media. We will be utilizing coil and slap built clay forms embellished with carved and sculpted wooden elements to create an animal like mask to hang on the wall. The clay forms can be decorated with a variety of techniques that will be covered in class. The finished wooden elements will be cleverly attached after firing. Students are encouraged to bring in other mixed media elements to add to their sculptural pieces to make them truly unique. This 8 week class will take place in the clay and wood studios, beginning with clay mixing in wood carving days and finishing with assembly.
This class will be co-taught by Margaret Josey-Parker (Clay) and Julia German (Wood)
