In these two images, you can see an example of unacceptable window treatments.
These light curtains have been made with a single pleat; the accepted standard within the industry are triple or double folds to form a pleat, the pleat would be a minimum of 90mm deep.
The choice of double or triple is manly influenced by the type and weight of fabric, the pattern and possibly the space available to stack the curtains when they are open.
i.e. When a lining is installed on a separate track usually it will have a twin pleat, a heavy velvet with a lining or a chintz type with interlining and a large pattern may also be twin pleated to show off the pattern or because of the bulk.
A twin 15cm pleat is often used where a more modern look is favoured or the windows are unusually tall.
The picture on the right shows totally inadequate fullness in these curtains and they will never hang properly.
Light weight/sheer curtains often come with a weighted base already on the fabric, this can be left on or if the client prefers the curtain can still be made with a standard hem.
This is personal choice but there may be issues if the curtain needs to be longer than average and there is not enough length to make a hem.
What to watch out for
Try and formulate a (realistic) budget even if you have run out of funds. Remember the temporary nearly always becomes the permanent so get help to make informed decisions. Budget difficult? Start with the same amount that you have spent on the floor coverings and work from there.
Ask your consultant for ideas and recommendations, this should indicate their level of experience and expertise, try not to make price the priority.
Ask where your curtains/blinds are made, what is the warranty, can you visit the workroom, can you view examples of work done?
Ask about tracking and installation.
Get the details of the job written in plain English so you know what you are getting and if you don’t understand the terminology ask questions.
Custom made window treatments should be made to a standard whatever the price range and should give you years of trouble free benefits and pleasure.
Selecting window treatments is a daunting task whatever stage of a project you are at, here are some tips before you start.
Think about what you need your window coverings to do. Privacy? Heat control? Accoustics? Etc. etc.
