Artists book. Five polyhedra are described and each is represented in a two-dimensional hand stitched illustration and in a cut-out which can be assembled into three dimensions: "I built the basic polyhedra, or platonic solids, into the pages of the book ... Each form lies flat on the page (like an architectural floor plan) with visible cut and score lines. The shapes can be lifted from the page (but not removed) and folded to create each polyhedra. The text is adapted from Euclid's Elements ... letterpress printed, and I hand stitched the name and a flat rendering of each three-dimensional shape"--Helen Hiebert http://helenhiebertstudio.com/products/tangential.
