It really is. However, if you are a total whovanator, and a Tom Baker fan, check out this website.
ClickThis website is dedicated to the many scarfs of Tom Baker. It tells you how to make your own Tom Baker scarf from every season. Also, it gives you the patteren, and exactly what yarn and needles to use. I love this website, and if you want to make your own (Like I am) than you should totaly look into it.
