Agree with the above, Nagoya is by far has the best value fabrics for curtains.

With the installation, I learned that Fo Sin at Ipoh street are not necessarily the cheapest (yet they are quite low and good value), as they offer now RM 5 per foot run of custom aluminum rails, without installer's fees. Other places like Nagoya offers RM 6 with installation included. That is for custom rails which are necessary to take if the rails need to be longer than 9 feet. If your rails are going to be shorter than 9 feet long though, it's much cheaper to get ready made ones from the likes of Houz Depot or hardware shops.
