These drawings are often records of journeys.  Some are actually done on named routes – Darlington to York, York to Grantham and so on, the marks all counted and recorded.  Some of them are developments of exercises for the Extempore Studies which Ian taught at Chelsea School of Art in the early Sixties.  Some pages are without notes.  Only bunches, waves, rectangles of dots and lines.  The marks are all.

(Ian once sat all day on a train travelling north making a tie-dye silk scarf, a large square, forming it with minute preciseness until it became a small bundle of knots and folds.  Other passengers gazed at the sight of his intenseness.  It did result in the most intricate piece of tie-dyed fabric ever seen.
