Narrow margins refer to a situation where there is very little room for error or deviation. This term can be used in many contexts, such as business, politics, and sports. In the context of a crossword puzzle, the term narrow margins can be used to describe the solutions to three clues: WHISKERS (8 letters), hairs (5 letters), and hairlines (9 letters). WHISKERS are long, stiff hairs that grow on the face of certain mammals, such as cats. Hairs are thin strands of protein that grow from follicles in the skin of mammals. Hairlines are the edges of the hairline, which is the line of hair at the top of the forehead.
