Much of decorating a room depends upon what room of your house you want to decorate. For instance, decorating a bathroom is a lot more limiting than decorating a living room. Each room has its own special needs depending on how you use it. Living rooms are usually more formal than family rooms, although many people only have a living room so it serves as both. In this case, the living room is a bit more informal.
Decorating room ideas abound on the Internet and in magazines. Here are a few ideas to get you started.
First, think of each room as a separate project. Even though you may be following a theme for your whole house, you won't be able to decorate it all at the same time. Be honest with yourself. Are the plans for each room realistic? Have you taken into account the function of each room? Are you going to hire an interior decorator? All of these things must be addressed before you start the project. Now, on to the rooms:
The way you decorate the living room is dependent on whether it's used only for when guests are visiting or if it is used daily by the family. Family use usually rules out white upholstery and carpeting because they do not hold up well to the abuse they would get. Fabric choices are also affected by the kind of usage it will receive. Choose fabrics and furnishings that are appropriate.
Here again, the way you use the dining room will depend on how it is furnished and decorated. Dining rooms, like living rooms are usually thought of as "company" rooms, while the kitchen or dinette are more likely used only for families.
The master bedroom should, by definition, cater to the man and woman of the house. It should be designed to meet their needs. The room should be comfortable and serene, although I have seen some bright red bedrooms that have been striking. Personally, I wouldn't get much rest in such a room. Privacy is also an important component if there are other family members around.
A guest room can be dedicated solely to guests or can be used as a combination guest room/office if space is at a premium. You may want to provide extra amenities for guests such as closet and drawer space, special towels and books or a small television for their use.
These rooms, by nature, should be casual. I have never seen a child comfortable among ruffles and formal furnishings in his or her room. Children usually "decorate" much of their space with their toys and "treasures." Low-to-the-floor storage and bookcases should be used to corral some of their belongings.
Kitchens can be one of the most difficult rooms to decorate unless you are willing to demolish the cabinets and countertops that are there. You can greatly change the looks of the room by using paint and buying new appliances. If funds are available, go for new flooring and cabinets as well. Many hardware stores have floor planning software that can help you get the best use out of the space available.
A bathroom can be updated with paint, new linens and fabric. Add a tall cabinet if there is space for it to use for towels and other bathroom items. Bathrooms can get messy fast when there's no place to store anything.
Look in magazines and on the Internet for decorating room ideas. Then, use your imagination and ingenuity to replicate the look with less expensive options. Interior decorating doesn't have to be expensive to look elegant.
