Most scarf curtains are very similar, so your choices are generally based on color, size and fabric. Choosing the best scarf curtains to complement room décor should probably start with color. Window size is also important, and the amount of coverage you want for the window. Scarf curtains are typically designed to drape around the window frame rather than fully covering a window, but depending on the length of the scarf compared to the length of the window, some window coverage is possible. Once you have determined the size you need, and the color you want, you can then make a decision on what type of fabric works best with other colors in the room.
Scarf curtains can be purchased ready made in a wide variety of fabrics, colors, and sizes. Most large department stores carry them, as do many home furnishing centers. When buying ready made window treatments, it is a good idea to look them over for flaws in the fabric and to make sure all the edges hemmed. This is especially important because some curtains and drapes are sold semi-finished. If you do not want to have to do any alterations or finishing on your own, be sure the ones you are buying are completely sewn.
You may want to consider having your scarf curtains custom-made. This is typically much more expensive than buying them ready made, but the end result may be worth the expense. Custom made window treatments give you many more choices in terms of color, style, and fabric. In many cases, with custom made curtains you may be able to achieve perfect color coordination within the entire room. You can even have your scarf curtains done in the same fabric as your furniture upholstery, though with the exception of some silks, most upholstery fabric is considered too stiff to work well with curtains that are intended to drape.
Whether you plan to buy ready made or have your curtains custom tailored, the type of fabric will be extremely important. Typically, the best types of fabrics for these window treatments are softer fabrics that drape and hang well. Sheer or semi sheer fabrics such as chiffon, voile, and gauze are all commonly used in making scarf curtains. Certain types of silk, such as dupioni and charmuse, also work very well, though silk is typically more expensive.
Measuring correctly for scarf curtains is considered essential. You should typically measure the width of the window, then the two sides, down to where you want the drapes to end. Some drapes come all the way to the floor on each side, others stop half way down. Either way, it is important to know how many total inches you will need to surround the window frame. Once that has been determined, add a few extra feet to allow for draping.
