In one of those bazaar twists of fate, this weekend seems to mark the unofficial opening of the Christmas shopping season. True, it's not even Halloween yet. But there are more Christmas bazaars coming up than you can shake an embroidered pillowcase at - 10 this weekend alone, and those are just the ones we've heard about. Dozens more are scheduled for the weeks ahead.

It's easy to understand their appeal. If you're looking for a one-of-a-kind Christmas present, look no farther than the nearest bazaar. At the Lutheran Church of the Good Shepherd, for example, there's a calico Noah's Ark for sale - complete with a 12-animal crew (Nov. 4). St. Christopher's in Springfield has handmade crib quilts (Nov. 4). Potomac United Methodist Church (Nov. 1 and 2) and Christ Episcopal Church (Nov. 4) specialize in mouse houses, sold with family and furnishings.

Or, you could hit the jackpot at one of the raffles, and present your loved one with a trip at San Francisco (Soorp Khatch Armenian Church, Oct. 20 to 22). Or a queen-size patchwork quilt - six months in the making by the women of St. John's Episcopal Church (Oct. 21).

As you make the rounds, fortify yourself with home-cooked food. Most self-respecting bazaars feature it, in the form of lunches, sit-down dinners, buffets, carry-outs or snack bars. In the weeks ahead, without traveling farther than the suburbs, you can sample Chinese, Romanian, Armenian, Asian, African, Latin American, Middle Eastern, English, Greek, Russian, English, early American, country-style and unspecified "gourmet" dishes. As the pounds add up, tell yourself it's all for a good cause.

To aid you in your bazaar-hopping, here's a list of what's coming up. But save a little time, money and belt notches - the list only covers bazaars scheduled through about Thanksgiving. We'll still got December to get through. OCTOBER
