Method for the manufacture, using a multi-head computerized machine, of an embroidered textile product with a design having three-dimensional effects, comprising the following steps: - creating the desired embroidery design using any suitable software for the generation of an instruction file that can be read by the computerized embroidery machine used; - providing a lower supporting layer consisting of one or more layers of water-soluble gauze, said lower supporting layer extending for the entire length of the machine and being attached to the anchoring frame movable above a horizontal surface beneath the embroidering heads; - placing on top of the lower supporting layer a plurality of layers, also extending in continuous pieces along the entire length of the machine and together constituting an upper supporting layer, chosen from polyester-cotton fabrics, non-woven polypropylene fabrics, even with different weights, and water-soluble gauzes; - activating the embroidering machine, with the heads all simultaneously performing the same programmed sewing-embroidery operations; - at each head, delimiting - by means of stitching - the outer perimeter of an embroidering area and possibly the outlines of two or more portions inside the area, while also securing the upper supporting layer to the lower supporting layer; - cutting the upper supporting layer in a direction transversal to their longitudinal extension, so as to separate the upper supporting layers of adjacent embroidering areas; - for each embroidering area: - partially or completely embroidering, in one or more colors, one or more portions of the embroidering area, at least one portion not being affected by the embroidering; - overlaying one or more thermogauzes on the embroidered portion(s) and embroidering three-dimensional elements of the design in different color(s), said phase also being repeatable depending on the three-dimensional and chromatic effects desired; - overlaying at least one layer of non-woven polypropylene fabric on the portion of the embroidering area not yet affected by the embroidering, and embroidering of said portion; - overlaying one or more thermogauzes on the last embroidered portion and embroidering of additional three-dimensional elements; - separating the embroidering areas and subjecting them to hot pressing and blowing to remove the thermogauzes. - creating the desired embroidery design using any suitable software for the generation of an instruction file that can be read by the computerized embroidery machine used;
