This striped tea cosy is a great one for inexperienced knitters as there is no shaping involved. It is fully lined so there is no danger of your teapot catching cold and the beautiful colours of Sirdar Snuggle Baby Bamboo really bring it to life. This cotton yarn is equivalent to 8ply or DK so you could easily substitute a wool or wool blend. I do not knit with acrylic as I find it hard on the hands and it is not very warm but it is certainly a more economical option. If you have not knitted with cotton before I would recommend knitting a tension square as it can feel a little different to wool.
