Take a dive into colour pooling and the journey that your multicoloured hand-dyed skein of yarn takes when you begin knitting it into fabric. Helen Reed, AKA The Wool Kitchen, and Wendy Peterson of Yarnsub.com explore the maths and magic that can make the difference between colours emerging as star dust or a smear across your sweater. Images and links to the yarns shawl and app mentioned in this episode are all available on the Knit15 Episode 4 web page.
