There is nothing I love more than a challenge, though my family might claim otherwise. When Carrie asked me if I’d ever made a full size version of the sleepsack I prototyped in the spring, I knew it was time to pull out the wool.
Since this needed to be warm, windproof and soft, three layers of roving would be required. Starting with handdyed passionfruit lychee corriedale roving from portfiber.etsy.com, I laid out a large piece of flat felt on a six-foot table, covering just about the whole thing. Next I drafted a second layer of corriedale and finished it with a third layer with solid merino.
Carrie had done some shopping online to find the perfect stroller sack, so she was able to guide me with the finer points of engineering. It had to be wide open at the bottom in case of muddy feet, but a pocket where clean warm feet could rest would also keep her son warm. I bought an extra long two way zipper for one side, and then inserted a shorter zipper on the other side so the front could be adjusted to the right height.
