Some tips for choosing living room curtains include considering the color and fabrics, how they should hang and deciding between custom and store-bought curtains. Custom curtains are more expensive, but sometimes a better choice for odd sized windows.
The color of the curtain fabric also needs to be considered. Bright colors work great in some rooms, but if the room receives a lot of natural sunlight, such as a living room, they may be prone to fading. However, if you like to upgrade the decor often and change curtains frequently, this isn't as big of an issue. Also try to avoid especially light or heavy curtains. Light curtains don't hold up well, while heavy curtains are difficult to draw open or closed.
