Among Karen Adams' reminders for devising "creative space" at home:

* Refer to your space with a definite name, such as "office" or "studio." In time your children, friends and neighbors will take the space seriously.

* Establish specific rules for children entering the space.

* Consider: lock on the door, intercom, answering machine or answering service.

* Check space for professional look. One idea: modern furnishings, even if in the corner of a Victorian kitchen. A clean contrast sets it apart from the rest of the room and defines the area "for work only."

* Select furnishings that perform double functions: file cabinets as desk or table bases; bookshelves as room divider; folding screen as display board.

* Have all your materials in the room so that you don't have to leave during your work time.

Or try renting space on a part-time or full-time basis. Some places to start in the Washington area:

* The WorkPlace: 1302 18th St. NW. Office space, typewriter, phone and message service available for $20 a day; $375 full-day monthly. Also other options. Word processors and secretarial help available at extra cost. For more information: Jean Levin, 223-6274.

* Library of Congress: Study desks, no-cost "rental" on long-term (1 to 3 years) and short-term (monthly) basis. Should be working on dissertation or book, with "a few exceptions." Bring own typewriter; no phones in study rooms. Approximately one month waiting list. For more information: 287-5211.

* Doctors' and dentists' offices: Check classified ads for sharing space in professional offices. Receptionist services also sometimes shared.
