Our Express Voile Curtains are all kept in stock in up to 12 different drops sizes, available by the metre ready to ship within 3-5 days! Once you have found your favourite design, and you've measured your window follow the simple instructions on the product page to order. Usually with voile curtains we recommend multiplying your window width by 2.5x but some people opt for slightly less (1.5x) and some for more (3x) depending on how much privacy you are after, or how much light you would like to let in. When choosing a drop, try to find a drop closest to your window size, and generally it's better to go shorter than longer. We find that you can usually go for a drop 5cm / 2" shorter without any problems, but a scalloped hem generally looks better short than a straight hem. If you need a long drop, our classic plain voile curtain is also available up to a 274cm / 108" drop. Every effort is made to ensure the drop of fabrics are as accurate as possible however due to the nature of fabrics there is a tolerance of 25mm+/- on all of our express voile curtains. If would prefer an exact size drop for your window, take a look at our made to measure voile curtain range, starting from only £5.95 per metre.
