To get the feeling of a room, think about when the building or structure that you are designing in was made. Was it made during a more modern period, and is it in a modern part of town (for example, downtown)? Or is it a home on a farm out in the country where there are cows grazing not 100 feet away? These things impact the look and feel of the rooms inside.
One of the cutest and most adorable looks in this day and age is the rustic feel of a country home. There are many different things that go along with this. For a home that has wood floors, this theme or style fits perfectly. Walls should not be painted to bright or flashy, and most of the furniture looks best in wood or natural fibers for this look.
Another asset to the rustic and country theme is the addition of country antiques. There are so many to choose from, and they can be found anywhere from rummage sales to discount stores to estate sales that are found in the newspaper or online. Often these gems go on sale for much less than what they are actually worth, but because no one sees the ad for a given estate sale, they are absolute bargains!
For people who can't find country antiques that are genuinely antiques, the look and style of an antique can still be fabricated with a newer item. There are websites and artists who specialize in this, or individuals and couples can do it themselves at home with tools like sand paper and "antiquing" or "crackling" paint to make items look older than they really are.
