A ribbon comprises a pair of facing strips and at least one string disposed between both the strips. Both the strips and the string are joined together at their one ends, and both the strips are joined to each other at a plurality of points on each of a plurality of lines spaced apart from each other in the longitudinal direction so that both the strips can be moved relative to the string in their longitudinal direction. Each strip has at least one slit extending in the longitudinal direction either between a joint in one end of the strip and a line adjacent thereto or between two lines adjacent to each other. A plurality of pairs of facing strips similarly joined by a plurality of lines spaced apart from each other in their longitudinal direction are also disclosed. |
