Abstract. Daily trouble in tying a necktie to get a good balance of the lengths of two tails of the tie was analyzed with an interest in the form of the tie. A sense of non-linearity often encountered in adjusting to get the good balance was elucidated objectively by experiments and a geometrical modeling of multiple-folds which essentially reproduces the tying process.

Keywords: Nonlinearity, Form, Multiple-Folds, Necktie, Semi-Windsor Knot
