Antonio de Sangallo the Younger was the architect behind the double helix curved passage at the St Patrick’s Well in Orvieto, Italy. He was inspired by the Bramante staircase at the Vatican, and my cowl design uses a double helix of stitches to create seamless garter stitch. Over the garter stitch a cable panel is worked. The ebook contains instructions on working a chart at the same time as helical knitting, including troubleshooting photo tutorials.

Pattern notes
The cowl starts with a ribbed edging. Helical garter stitch is then established, with a cable panel worked between markers. The cowl is completed with a second rib edging. Cable panel instructions are provided in both written and charted formats.
