Curtains are an inseparable part of any home. But if you choose them wrongly it can lead to no sunlight or air in your home.
If the window lets in lot of sunlight during the day it is better to buy thick cotton curtains. This will keep the room cool and comfortable. On the other hand, if there is lot of sunlight only in the morning, a sheer curtain is good enough. The room will not be dark and there will be enough light throughout the day.
The colors of the curtains can be matched to your interiors for a better effect.
