A collaboration with what began as New York City's tiny neighbourhood knitting shop in Soho and is now a thriving online store housing their exclusive own brand knitting yarns - PURL SOHO. Purl Soho are the yarn sponsors for the Construction Knitting Book supplying me with all the natural fibre yarns where I write about their properties in the Chapter 'Classification of Yarns and Fibres'. I have designed a pattern particularly for Purl Soho's Tussock Yarn,which is available as a download on this website. The Construction Knitting CIRCLE V.1. pattern is knitted in this superfine 60% Kid Mohair and 40% Mulberry Silk yarn blend. I wanted to maintain the weightlessness of this yarn by knitting it on bigger needles so that it has a cobwebby finish. The circles when joined cascade like clouds over the body and maintain the structural form and shape due the the seam lines. This is a gorgeous garment and object and is worth every bit of patience and time to handknit each circle.
