Black Cat Systems today announced the release of Knitting Wizard, an application that allows users to create their own custom knitting grids and diagrams. You have complete control over the diagram characteristics: select the number stitches and rows per inch; specify the total number of stitches and rows; select from a dozen standard paper sizes, or custom create your own; diagrams saved as pdf files, so you can print them whenever you wish; and more. Knitting Wizard is priced at US$19.99.
