Shades have come a long way in recent years. They can be made of vinyl or any number of fabric types, from simple to ornate. You can choose based on what your goals are. And the beauty of having so many choices is that you don't have to pick just one. You can change them seasonally, or on a whim.

Do you want them to control the light in the room? Perhaps you need to darken a bedroom during the day for sleeping, or you'd like to let light in. You can find a window covering for this. Room-darkening shades are generally lined with heavier material, rendering them opaque, and thus perfect for darkening a room.

Do you want privacy? Your choice should offer maximum protection from the outside world. You'll want a heavier shade to ensure your privacy. Layering window coverings such as a curtain and a valance over it can help further your goal of having privacy.

Do you want to deaden sound? Depending on the shade you choose, you can find one that muffles sound better than the rest. It won't stop sound from entering your home, but any barrier you add to your window will help dampen sound.

Do you want something that will help insulate your home? Many times, drafts are caused by cracks around windows and window sills. These can be blocked somewhat by shades and other window coverings, and help keep energy costs down. Vertical blinds, curtains and other window treatments can help insulate your home as well.

Do you simply want to decorate your window? You can create ambience in a room through your window treatments. The wide selection of styles, fabrics and colors make it easy to find something to fit your style. You can bring them to the forefront of your room, or have them play in the background.

Another consideration is whether you'll display them with other window coverings such as curtains or drapes. You can put them on display, with the curtains in a supporting role, choosing bold and vibrant shades, and coupling them with simple curtains. Or you can choose colorful curtains with understated shades.

The options are endless. With a little knowledge under your belt, you should be able to make a great choice.
