Remember the Doctor’s absurdly long scarf? Sure you do. It is an iconâ€”the be-all-and-end-all of scarfdom. Believe it or not, there is an entire site devoted to the history of this 20 foot long, multicolored beastâ€”and it includes patterns for several versions of the scarf used during the series. So, if you have some handy knitting skills, you can make your own. Or, as the site suggests, purchase a pre-made version found on sites like eBay.
