“That’s Macy’s little room,” says homeowner Mary Jennings, referring to the 10-by-10-foot nook off her master bedroom — an area so tiny it might have been tricky for some designers to outfit. Knapp, though, created a cheerful design centered around Jennings’ 9-pound Bichon Frise, who naps daily on the custom 4-by-6 hand-knotted Jaipur rug. Jennings uses the room, too, mostly for reading on the contemporary – and comfy – chair-and-a-half by Sherrill Furniture.
