Protocol is a free, purpose built knitting pattern writing tool with a custom paginated document editor built from scratch, a live gauge recalculation engine that updates every stitch count in your pattern instantly, and a stitch chart generator that writes row-by-row instructions automatically as you draw. Built on Craft Yarn Council sizing standards. No spreadsheets. No duct-taped Google Docs workflow. Just a complete, formatted pattern document, ready to export as PDF.
