One-Sheet Plywood Staircase
I’ve always enjoyed the mental exercise of planning a piece of plywood furniture to maximize efficient use of the material in the sheet stock, so I tend to appreciate good ones when they pop up, every now and again. Here’s a nice example, a 32-inch-tall staircase, with four one-foot steps, from Instructables user Pilgrim55.
