My son wanted a Doctor Who scarf. So here it is. I have actually never watched the series so I had to troll through Ravelry to find examples. According to my son, there are also different scarves for different seasons of the series. This color arrangement is from season 14.
I used size 10 needles and cast on 50 stitches. Then I just knitted every row, following the picture. I have to admit that I don't like fringe on scarf, and I especially don't like it on this scarf, but my son said it was important. It's all a matter of taste, I guess.
Also my son is in Los Angeles. I am not sure he really needs a scarf for anything more than style. But I guess that's also a matter of taste.
