SINGLE PLY PROJECT

The Single Ply Project is a design and woodworking apprenticeship that pairs six emerging designers with six mentors to explore the intersection of creativity, craftsmanship, and problem-solving. Each mentor builds their own chair while assisting their student apprentice in theirs. Through sketching, prototyping, material exploration, and fabrication, participants learn how constraints can fuel innovation while developing foundational skills in design process and woodworking. The program culminates in a public exhibition where all twelve chairs are displayed, celebrating the creative process and demonstrating how a simple material can become a vehicle for design, storytelling, and community connection.

  • Dates: July 12, 19, 26th + Open Lab Times throughout August

  • Location: Portland, OR

  • Cost: Suggested donation of $100 (sliding scale)


Inspiration: ENZO MARI

Enzo Mari’s defining furniture concept, Autoprogettazione (1974), is a radical DIY design manifesto empowering individuals to build their own practical furniture using only raw pine boards, nails, and a hammer. Mari's primary goal was the educational process of "making" rather than the final physical object.

The Enzo Mari chair is constructed from pieces of pine, all of the same width and thickness, cut into various lengths and pieced together to make a simple yet very solid piece of furniture. An incredible symmetry is created through the use of only one material, which also makes the chair easy to construct with zero waste. Anything additional to its purest function has been removed. Despite this apparent minimalism and functionality, the finished product has an individual character, a hand-made craftiness and a uniqueness that speaks of Mari’s quirky design spirit. The chair is part of Mari’s larger autoprogettazione project, which translates roughly as “self-design” and involves detailed instructions on how to build and customize items of furniture using simple materials, including readily-available timber, a hammer and nails. The project is composed of nineteen designs that include nine tables, three chairs, a bench, a bookshelf, a wardrobe, and four beds. The aforementioned chair, from this perspective, is part of a larger puzzle that talks of sustainability, creativity and experimentation in a world dominated by mass-produced and stylised design objects.


CURRICULUM

  • Goal: Introduce basic woodworking concepts, design principles, and the material (plywood).

    Objective: Understand the properties of plywood, basic woodworking tools, and how to conceptualize a chair within the constraints of a single sheet of plywood.

  • Goal: Begin conceptualizing and sketching chair designs, followed by creating blueprints and models.

    Objective: Develop design ideas, create scaled sketches, and prepare for construction.

  • Goal: Begin cutting and assembling the chair based on blueprints, applying basic woodworking techniques.

    Objective: Develop hands-on skills in cutting, sanding, and assembling the plywood chair components.

  • Open Lab Time: work with your mentor to finish your project

  • All 12 chairs are shown in an exhibit showcasing the process and final products
