Finished! I think it looks pretty good, I am pleased with it. Not quite as wide at the top as I would have liked but I did not have any more yarn so i added the little ties at the corners just to make sure it is secure round my neck.
This is my own pattern. Cast on 3, then yarn forward either side of the central stitch with 6 stitches of garter stitch at each edge to stop it from curling up. A bit of short row shaping at the top to straighten the top out a bit and then a few rows of garter stitch.
I will be sporting it tomorrow on route to the bus stop.
