Hi ayane,
I got my roller blinds made to measurement by Jimmy Textile.
http://www.jimmytextiles.com/ I went to the main branch at Tanjong Katong Complex. The boss, Jimmy (old man) came to my place personally on a Sunday morning and we went down to the shop on either Monday or Tuesday night to select since hubby could not decide on the colours and patterns. tata and it was ready in a week. Usually could be done within a week.
Actually I never imagine that I'll do roller blinds for my new house as I actually prefer those ready made curtains which I used to change every week. I swear I never like roller blinds as I thought it'll be collecting dust. But its easier to clean compared to curtains which u'll have to change to clean it. Roman blinds (usually those used in office) are more prone to dust but roller blinds are ok. At the old house, I've so many colourful ones which I've already given away recently
This afternoon I was at causeway point and saw many ready made curtains (cartoons)...oh how I missed those curtains. But frankly speaking, its too time consuming to change it every week and I also need storage place for these curtains so I'm actually contended to having roller blinds
I paid around $750 (estimated as dont have the invoice now) for 3 bedrooms. I believed new flats cheaper as the window panels are smaller.
Gd luck and got house pic to show us?
