ON THE ANTIQUES TRAIL IN LONDON SHOPS
Every month or so, the New York decorator David Easton comes to Europe to go shopping. Hardly pleasure jaunts, these brief trips typically include stops in Lisbon, Madeira, Paris and London, days crammed with appointments, darting from place to place in search of the antique rugs, linens, fabrics, furniture and the like that he cannot find in America. ''Engish and European dealers tend to have the larger, more unusual pieces,'' he says. ''American dealers hesitate to bring in such things.'' ''It's like planning a military campaign,'' Mr. Easton explained recently, leafing through typewritten pages of items he wants for clients and a hand-written itinerary of the places he will go. His company, David Anthony Easton Inc., designs both houses and interiors. Known for his British country-house look, Mr. Easton has created large Georgian-style homes for wealthy American clients, most of whom insist on anonymity. So London is a focal point for the 49-year-old designer, not only for concentrated shopping stints, but also as a source rich in material for research in architecture and furniture.
