Corner to Corner Blanket
this the tagline
The Corner-to-Corner Blanket Wizard helps you plan a diagonal, bias-knit blanket from any yarn, any gauge, and any machine. Enter your finished size, yarn weight, and stitch/row gauge, and the wizard calculates shaping, needle counts, and the increase/decrease sequence for smooth edges and a perfect square or rectangle.
You can also explore variations, choose your construction style, and download a step sheet for your machine.
It’s a quick way to go from “I think I want to try this project” to “I know exactly how many stitches I need and how to knit it.”
