Curtain ideas depends largely upon the size and style of the doors and windows. There are certain other factors which have to be kept in mind while choosing the right kind of curtains for your bedroom. First of all, you have to decide on the amount of light you want inside the bedroom. Most importantly, the curtain should give you a sense of privacy when you are in the bedroom. If you are living in the countryside then you may not have a house close-by, but in a city, privacy of the bedroom is a vital factor which cannot be overlooked. For Small Windows You can use long, hanging curtains that extend below small windows. As a result, the size of the windows get covered, making it seem that the window is large. A flat Roman shade can add a style statement to a bedroom that has small windows. The shade can be made of soft fabric, or woven wood. These materials are semi-translucent, and hence, the outline of the window will be visible during the day. If you wish, you can use a blackout lining under the fabric for the sake of privacy. For Large Windows The challenge of large windows lies in the fact that they require a large amount of materials for the curtain. You can give a layered look to the large windows. For this, you have to use a multiple number of sheets of sheer curtains that will partly cover the window. These sheets will provide adequate support by a heavy panel of fabrics. This gives an interesting look to the large windows. For more decorative windows, you can use fabric valances that are made of hardboard with a heavy fabric padding. For Arched Windows When you have arched windows, you really don't feel like covering it up with curtains as they have a character of their own. However, since some amount of privacy is essential, you have to put curtains on them. If the windows are facing your backyard then I would like to advise you to keep them without a curtain. Otherwise, keep the arch of the window uncovered and use a Roman shade of thin texture to cover the rest of the window that lies below the half circle. This way the beautiful shape of the window will not get affected. You can also fit a long rod on the wall near the ceiling and hang long, lightweight curtains or sheers, so that they do not cover up the design of the window, and can be pulled away from the window during the day. For Bay Windows Bay windows in a bedroom are excellent architectural features which add depth to the room. Curtains chosen for bay windows should be such that the natural look and feel of the windows do not get affected. You can hang a number of sheer panels over each section of the window. This way you can ensure plenty of sunlight inside the room during the day without hampering your privacy. In this manner, a nice flow of fabric may be created. If you do not prefer a formal look for your bedroom, then a cafe style curtain is the right choice for you which will cover only half the window. To make your bay windows look more colorful, you can place a valance at the top of the window. The color of the valance should either match or contrast with the color of the cafe curtain. For French Doors When your bedroom has French doors, then you have to select curtains that reduce the visibility and maintain the kind of privacy that you expect in a bedroom. Moreover, your movements through the doors should not get affected because of the curtain. The materials that are most commonly used on French doors are silk, muslin, and sheers. Curtains with lace look wonderful on French doors. You can also use French polyester voile for this purpose. This material has a refined texture which diffuses the light very beautifully. Selecting curtain ideas for bedrooms is a challenging task because it should be in sync with the style and feel of your bedroom decorating ideas. Once you have successfully done so, you will get a sense of fulfillment.
