I have be fan of Tara Sfree) for few years. Her YouTube is full of yoga sequences one can do. When I found out she learned how to knit, I liked her even more. Matter of fact, I tend to like people a bit more when I learn they know how to knit (or crochet, or sew).
Tara has teamed up with Wool and the Gang (how awesome is their name?!) To create yoga knitwear. Some of my favorites:
Hot Top (pose included for free)
)You can pre-order the items already made or have the materials sent to you and make them yourself.
