It is all moss stitch and each stripe is a whole ball of yarn. The yarn is Jaeger Matchmaker that I picked up in a charity shop for a bargain price. I love these colours, especially the purple, there is quite a lot of yarn left so I can make something for myself too.
Sorry about the spot in this photo, my camera keeps doing funny things. The blanket measure about 110cm wide and 150cm long and feels lovely, I think it looks quite good too!
