We have a living room with a very high ceiling and a wall of windows that extend very high. The room is quite cold in winter and we would like to add some curtains, preferably something velvet for warmth. We need a length of 350cm and two widths to cover of 210 cm and 165cm. I'm aware this is not going to be cheap. Are there any companies that people would recommend, or would a local seamstress be the best option perhaps?
