Another rule of thumb for grouping or clustering objects is to stick with odd numbers. For example if you are grouping candlesticks on a mantle, try using one tall, one medium, and one short for a more interesting look. Low baskets or trays are a great way to display a bunch of dissimilar items together and make them cohesive and feel special.
Some of my favorite accessories to use in a room are books, they are relatively inexpensive and a great way to incorporate a clients personality and preferences. You always want to give the appearance of books collected over time, so stay away from color coordinating the spines. Instead alternate the colors for a richer look. Keep in mind that the arrangement is more pleasing to the eye when the books are not lined up on the shelves. Try standing some up, while laying a few down, adding frames and other objects to give a more personal feel instead of a "library" look.
Candles are a great way to bring in some lighting and ambience in the room. Try using scented candles but stick to whites and creams so they are not demanding your attention. Display them in hurricane shades or clustering them on a tray in different heights instead of scattering them about the room. There are great options on the market for wickless candles so you never have to worry about them being a fired hazard.
Fresh flowers are a must in any room, just a simple arrangement of calla lilies is enough to liven up a room.
I usually have trouble convincing my male clients that no room is complete without a couple of pillows in the sofas and chairs; they just can't visualize it until they see the finished product. Pillows and throws are a great way to bring color into the room, and the feeling of homeyness and comfort, especially if you are working with a leather sofa. Just keep in mind that there needs to be comfortable space to sit. Here are some great options from Surya that will set the tone for a beautiful room.
My biggest pet peeve is a room without proper lighting. There needs to be various types of lighting such as an overhead fixture on a dimmer switch for general lighting, lamps for task lighting, accent lighting for adding visual interest to art or a houseplant or to highlight a special texture on a wall, and ambient lighting to create different moods in the room.
Finally, please resist the temptation of overdoing it! If it looks like it's too much, then it's too much! On my decorating projects, I always take more accessories than I think I need. Even though I've done this tons of times, you don't know how a room is going to turn out until you are there. Just remember to keep your receipts for those inevitable returns.
