Going Underground. . .

While I'm waiting for a chance to get some Mind the Gap yarn (the dyer can only do so much at a time and it sells out quite quickly), I'm also coveting this boxed set of twelve books, by twelve different writers, all celebrating 150 years of the London Underground.   The writers include John Lanchester, Lucy Wadham, William Leith and John O'Farrell, and each has written about one of the tube's lines.  I really like the design of the collection.  And I want to knit a colourful scarf with the yarn to go along with it.
