There have been at least seven distinct scarves over Tom Baker's time as the Doctor.
The earlier seasons, The Season Twelve, the Season Thirteen and the Season Fourteen were cut up and combined to make the Season 16 &17 Scarf.
One of these scarves, the Shada Scarf, was in the possession of JNT and is now in a private collection in the US.
The Season 15 was only used in three episodes, Image of the Fendahl, Underworld and The Invasion of Time, and then it totally disappears.
The Season 18 scarf has also totally disappeared except for a slightly different version that was at the Doctor Who Museum in Blackpool.
Has anyone else seen one?
I have knitted over fifty scarves myself and I'm desperate for more information on the original scarves.
I would be more than happy to help people knit scarves for themselves, so feel free to message me with questions.
