I've recently tried this shop in Wanchai, learned about this contact from one of the thread in geobaby. They have good workmanship and the ladies are friendly, lots of imported fabrics and could do more then curtains. This is the name of the shop and address, look for either Polly or Fiona. Not the cheapest around but very professional and efficient.
