If your wallpaper is as dull and timid as, say, a wallflower, you could use some professional advice.

First, examine your needs. Will the room you're papering need washable wallpaper? Is rugged wearability a must? Does the price play an important part? Once you know your needs, shopping will be easier. Here are a few types of paper:

• Machine-printed papers are the most common and the most moderately priced. The reason for their popularity is that there's an almost-unlimited number of patterns and colors. They're printed on high-speed presses, which reduces manufacturing costs. If you're hanging the paper yourself, look for pre-trimmed paper. The selvages are cut off, so your work is made easier.

• Hand-printed papers are more expensive than the off- the-press type. Though this type of wall covering is called "paper," you'll find that hand- painting also is done on linen, foil, vinyl and silk. These papers usually aren't pre- trimmed and are delicate. Use a professional hanger.

• Washable paper is the most sought after for kitchens and baths. There's a range from wipe-off to scrub-to- your-heart's-content. The plastic-coated type allows you to wipe off dirt with a damp cloth. Vinyl-impregnated papers are the scrubbable kind.

• Pre-pasted papers have the "stick-um" already on, so all you have to do is wet and apply, which is a great work- saving advantage. Another advantage is that they often can be applied right over existing wallpaper if the old paper is in perfect condition.

• Strippable paper is just that. It peels off the wall easily.
