That fabric is one quarter of a piece Lina gifted me with last year. I've been stingy with it so I have enough left to do the other three seasons. I would have made it into a pillow yesterday if I'd got round to getting thread for the sewing machine!
Edited to add: I wish it was just one train journey - what a lot I'd get finished! It took about a month of 30 minute journeys and a couple of lunch hours. I don't always get to stitch on the train - I sometimes get chatting to a couple of fellow commuters instead. And train stitching is slow - trying to find those holes on a bumpy journey can sometimes be frustrating. Every little bit adds up though!
