Thank you for your quick responses. My problem is compounded by the fact that there is welting (piping) on three sides and as such sewing in for the original stitch line would cause a problem. Maybe my best option would be to make a totally new cover. I have included 2 images; the first of the 'problem' seat, the second of my first attempt at making a new cover which I needed to do for the other seat. Many thanks for all your help, Marcel
