The fundamental ideas of the Construction Knitting Book is that "knitted fabrication enable the creation of not only flat surfaces, but curved and ruffled surfaces that apply and interpret three surface geometries – plane, spherical and hyperbolic" (Black, S, 2024). In other words, straight, curved and ruffled. Experience this magic in knitting as the book guides how to easily change shaping (increasing and decreasing of stitches) to adapt the surface geometry of knitted structure from basic plain knitted horizontal rows and vertical lines of stitches.
