Years ago, on a computer bulletin board, I found a text file with the instructions for making the famous Tom Baker Scarf. In January of 1991 my aunt spent 40 hours knitting one for me. This was during the Gulf War TV blitz. Sorry, she's not taking requests.
Here's a picture of my scarf taken on 11 March 1997 with a digital camera. The original text file follows the picture.

This pattern was taken directly out of the Whovian Times.

A note from my aunt who did the knitting:
2-Mar-2003
It seems amazing that it's been 11 years since I did that...but I think of it every January/February. It is also on my mind with war being the topic of the news. As a curiosity, I calculated the number of stitches ...it is 48,360. At 40 hours, I averaged 1209 stitches per hour. That blew my mind!!! Just thought I'd share the numerical madness.
