A method for the manufacture of a semifinished material prepares such material for the subsequent production of a flower-like or petal-like decoration. For this purpose an initially flat band ribbon or tape material, that is sufficiently flexible for the subsequent folding to form pleat-like folds, is provided in its lengthwise direction with at least one drawstring which itself is also sufficiently flexible. The drawstring is secured at spaced intervals to the flat material, so that the drawstring is free from the flat material outside the securing points or areas. In these free intervals or spacings the drawstring is not covered by the flat material such as a flexible ribbon. At least one longitudinal edge of the flat material is provided with a non-linear contour which subsequently helps forming a flower or petal-like appearance. The free or non-covered sections of the drawstring are so dimensioned that a desired folding size of the pleat-like folds, to be formed later simply by pulling on the drawstring, is achieved.
