Curtain Workshop near Tooting Bec. I used them for shutters, blinds and curtains and they were excellent. Very helpful when choosing from different options and the fitting was great too.
E & A Wates make roman/roller blinds and curtains at their showroom/workshop in SW16, they also have a huge range of fabrics to choose from. They have a sale on furniture at the moment: www.eawates.com
