Eleven 8×10" Gelli plates packed for classroom and workshop use. The 8×10 is the most popular individual size in the range, so a class working in this format produces results that match the workshop tutorials and books most students will go on to use. Eleven rather than ten gives you a demo plate alongside ten student plates, or covers a small group with a spare for the inevitable mishap. Gelli plates were developed by Joan Bess in Pennsylvania to replace traditional gelatin printing plates — too fragile, too perishable, too much hassle in a teaching environment. The Gelli version uses mineral oil and proprietary binders to deliver the same tacky printing surface with none of the upkeep. Each plate cleans with soap and water and survives indefinitely if students treat them reasonably. Class packs are the right buy if you're equipping an art room, running a printmaking workshop, or teaching mixed-media to a group. Pair with acrylic or water-based block printing ink, brayers, stencils, and printing paper, and you have a complete monoprinting setup that works from age 8 through adult. No press required.
