Clay • Adult • Level II THROW DOWN • Wed (Aug 26 - Oct 14) • $300 • HILL
with Colleen Grande
Inspired by the show The Great Pottery Throw Down, this class is designed for intermediate students who want to break out of their comfort zones, be challenged, and have a ton of fun doing it.
Each week will bring 2 prompts:
- The Technical Challenge: A fast-paced surprise designed to test your skills. Think speed-throwing a teapot, throwing blindfolded, or racing to create five identical bowls.
- The Main Make: A focused project where you can let your creativity shine. You’ll tackle complex, multi-piece creations like nesting bowl sets, thematic tile collections, full dinnerware sets, or tea sets.
Is this class for you? If you have the basics down and are looking for a unique, high-energy challenge, absolutely. This class thrives on community and shared experience - it's at its best when everyone jumps into the challenges together.

Metal • Adult • Level II - Welding Sculptures • Thu (8/27/26 - 10/15/26) • $725 • MAIN
with James Makely
In this Level II welding sculptures class, students will explore the construction of geometric forms by combining various fabrication processes to assemble a complex steel sculpture. The course guides students through the entire creative cycle, from initial design, layout, and joint-preparation techniques to final detailing. Participants will expand their cutting skills using a bandsaw, plasma cutter, and cutoff wheel, while studying how materials intersect in different structural configurations. By building upon foundational welding skills, students will learn to fit and weld multiple pieces together, finishing their multi-faceted forms with handheld grinders and sanding equipment to create smooth, clean surfaces. These versatile techniques can be used to fabricate steel sculptures and complex objects of any scale for both indoor and outdoor display.
This is a level II class and and welding experince is needed. Our Metal Studio does have some safety basics before anyone is allowed to join in the fun (failure to meet these requirements will result in not being granted access to the equipment):

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!
