Voiles can be a simple and elegant way to enhance your home. They are more versatile and sophisticated than the more traditional net curtain and can be a luxurious way to add a bit of privacy and soften glaring sunlight.
Whilst sheer fabrics aren't as complicated to order as standard curtains, you don't need to worry about interlining and backing fabrics, there is still plenty to consider:
A gloss sheer can add a touch of drama to any room
The modern way to hang voiles is in soft waves, which is achieved by using a wave track and a generous amount of fullness/gather. You will need a wave heading on a pre-set wave track. Because sheers are thin you can get away with a "fullness" of 2.25 or 2.5. This is the amount you multiply the width of the window by. The more elaborate heading style you require, the more fullness you will need. You will need to leave a good amount of space for the stack back, well away from the edge of the window to maximise light, and decide if you'd like the curtains to part in the middle or retreat to one side. All curtain ends will be trained to sit in (face towards) the window/wall so that you are never viewing a side hem. This adds to the required fabric width.
