Welcome to Quick Print! These one-time classes offer students a crash course in one specific type of print without the commitment of a multi-week class. Perfect for beginners, experimenters, or anyone looking for a fun way to learn a new skill fast!

Reduce, reuse, reimagine with Tetra Pak printmaking! Printmakers have a special kind of curiosity—the type that makes you look at an empty carton and think, "I bet I can print with that." That instinct to experiment and repurpose is exactly what led to Tetra Pak printmaking.

Tetra Paks are those familiar, lightweight cartons used for shelf-stable liquids like juice, milk, and broth—lined with a thin layer of aluminum to keep contents fresh. The aluminum layer takes ink surprisingly well, holding fine lines and details with precision. Scratch in your design, ink it up, and pull a print. Suddenly, that empty carton has become something entirely new.

It’s art with a sense of resourcefulness—proof that the most inspiring materials are sometimes the ones right under your nose. Come spend the evening experimenting with us!
