Loop string fixing device and method for providing loop string fixing device

A method for providing a loop string fixing device, comprising:

• providing a stopper including a front plate that is formed with first and second through hole rows laterally spaced apart from each other and extending in a height direction, in which each of the first and second through hole rows includes upper through holes and lower through holes located below the upper through holes;
• providing a loop string, the loop string being a string curved at a middle portion to form a loop part and including first and second string extensions extending from the loop part and first and second string end portions at ends of the first and second string extensions;
• providing a loop string fixing device by assembling the loop string and the stopper so that each of the first and second string extensions passes through the corresponding upper through holes from a back surface (B) toward a front surface (F) and each of the first and second string extensions drawn out to the front surface (B) through the upper through holes passes from the front surface (F) toward the back surface (B) through the corresponding lower through holes.
