did all my curtains and railings from ikea for my 5 bedroom rooms 5 yrs back.
all the railings cost 200 plus only. no need to worry so much. cos they will drill so it will fit in.
curtains, i bought block out sun and sound type from ikea, cost me $150 plus last time. the rest of the curtain are really cheap type from ikea, i bought $8 ones - 2 pieces of curtain for my living room.
my view is as long as u match up nicely , it will look nice.
my current condo is renovating, am thinking also of ikea for curtain railings and curtains and roller blinds.
my motto is buy cheap curtain, dun like.. just throw. if u feel like it, can always buy curtains from outside.
my condos parquet bedrooms will hv wooden roller blinds, it will match super with my platform bed - parquet colour and wood laminate colour warbrobe. and my vanity top is sand marble colour quartz top. the effect will be gd. ho ho
