My wife ordered from Merlin Curtain (they got no website though but they are here in Penang). She ordered vertical blinds instead of curtains, for 3 windows only (76 sqft). They are charging us RM400 only (including installation/delivery). We're expecting the blinds next week (Monday).

Price of vertical blinds is RM5.30 per sqft but my wife said there are other choices of blinds or curtains that only costs RM4.40, RM4 per sqft (price depends on choice of design).

I think the price of the blinds is reasonable. It's not washable (just vacuum the dust) but if it will last for 5 years or more... I guess it is a-OK.
