The term 'long, narrow strip' can be described by two crossword solutions: SWATH (5 letters) and RIBBON (6 letters). A SWATH is a broad strip of land or a wide area that has been cut or cleared. It is often used to refer to a path cut through a field of grain or grass. A RIBBON is a thin, long strip of fabric, usually made of silk or satin, that is used for decoration or as a trimming on clothing. Ribbons are also used to tie up hair or wrap around gifts.
