with Renate Mairie

Calendar Jun 24, 2026 at 5:30 pm, runs for 8 weeks

In this cross-studio class you will first have 4 weeks in the printmaking studio to learn the basics of carving into Lino to make a custom 9” x 12” print on paper.  You will achieve techniques that can be applied beyond this class and create a Lino block that you can print again.  

After completing your 9" × 12" print, you’ll build a custom hardwood frame in maple, cherry, or walnut to showcase it. Starting from rough lumber, you’ll mill stock to precise dimensions using the jointer, planer, table saw, and chop saw. You’ll cut accurate miters and assemble the frame with glued, splined joints in a contrasting wood species for added strength and a refined accent. Finally, we’ll apply an oil-based finish and install your print, so you leave with a professionally crafted frame ready to hang. All materials are provided.

All supplies and materials will be provided, but if you have extra elements you'd like to add, students are encouraged to bring them in. 

This class takes place in the print studio and wood shop at Groundworks Art Lab Main at 3750 Canfield Street Boulder
