When most people buy their first house, they start to think if there is a way to make it more comfortable and more welcoming. They also want a place where they can find themselves at home. If you are average in this sense then there is no better way of doing this than actually getting everything right and coming up with ways to beautify the space. Add paints in colors you like and pieces of furniture you find comfortable, paying attention to details as small as window valances.
While most people don’t care the least bit if there is a piece of cloth above their windows, others find it amusing to work at their rooms. They are those who understand the importance of putting everything at its perfect location; and they are those who actually like working on them. This is their hobby and there are not many details more important than the windows. They are your view to the outside world, and usually large in surface area so they should be taken seriously from design perspective.
A large clean surface may give the room a feeling of openness, but too many of these surfaces can make the room feel empty and that is a feeling no one wants to feel when they finally get home from work. Valances and window treatments deal with the root of the problem offering a great variety of options to match well with the design of the room.
