Do you collage? Do you decopage? Do you recycle? Do you upcycle? Do you ever hesitate throwing something away because you just know there is some type of project you could use it for? Welcome to collagraphy, my friend!

Collagraphy is a printmaking process in which found materials are glued or sealed to a rigid substrate (paperboard in this instance) to create a plate. Once inked, the plate becomes a tool for imprinting the design onto paper with the resulting print termed a collagraph. The term "collagraph" is derived from the Greek word koll or kolla (also where the French get "collage"), meaning glue, and graph, meaning the activity of drawing.

This 4-week class will run you through the basics of creating a unique, free-form collaged plate, mixing and applying ink, and using our printing presses to make totally original artwork that you can treasure forever (instead of hoarding weird bits of garbage you can't stand to part with).

Ages: 16+ 

All supplies and materials will be provided. Bringing your own found objects are welcome and encouraged!

This hands-on blacksmithing course is designed for young makers who want to explore the ancient craft of blacksmithing in a fun, safe, and engaging environment. Students will practice traditional blacksmithing techniques such as tapering, bending, and twisting, while learning to use the forge and anvil. Alongside developing valuable crafting skills, participants will gain confidence as they complete a range of creative projects, including but not limited to: a bracelet, hook, and snail.

Throughout the class, students will receive expert guidance on shop safety, fire management, proper tool usage, and how to work effectively with the anvil. By the end of the course, each participant will have the opportunity to leave with their very own handmade metal projects and a basic knowledge of blacksmithing.

Color plays an important role in any visual medium; it impacts how we see, perceive, and interpret visual stimulus and is therefore an important tool for any artist. This unique class will provide an overview of the role of color in any visual medium while using hands-on printmaking methods as a practical and expressive means of exploration.

In this 8-week class for intermediate to advanced artists of any medium, we'll practice color theory and cover the basics of making a reduction print by carving linoleum blocks to create unique, one-of-a-kind prints.

Single block, multiple colors: Unlike traditional color printmaking where separate blocks are used for each color, reduction printmaking uses only one block,carving away areas after each layer is printed, resulting in a layered, reduced print to create a multi-colored image.

This is a level 2 class, students should have some level of printmaking experience to participate.

Ages: 16+ 

All supplies and materials will be provided.
