Print • Adult • Level II: Woodblock • Thu (8/27/26 - 10/15/26) • $290 • MAIN
with Jax Perna
Woodblock printing has a rich history, and was used to create both text and images on the same block. Also known as woodcut, woodblock printing is a relief printmaking technique where areas of the wood block that are not meant to be printed are carved away, leaving the image areas raised.
This 4-week intermediate to advanced level relief print class expands on the basics of relief and will include weekly instruction on techniques including carving, mixing and rolling ink, measuring and tearing paper, using the printing press, and making an edition of prints.
Ages: 16+

Learn to turn! This class will be an introduction to using the lathe - a machine used for shaping all manner of cylindrical forms (think bowls, vases, furniture legs, even pens!).

From practicing spindle turning to learning how to make bowls, we will learn the two major turning techniques that can be explored to no end with further practice. This class will be as hands on as any class can, wasting no time before getting students turning with tool in hand (don’t worry, we’ll go over safety basics too). Beyond the basics we will practice, practice, practice. You will not want to turn your machines off!
