A method of manufacturing a multilayer fibrous product. The product comprises at least two overlapping layers， each of which has a different fibre composition， and in the production of the product， chemical short stock is used at least partly. In the method， short stock is brought to a screening stage where fines， which pass a screen having an average hole size of 0.2-1.5 mm， are separated from it， in order to prepare at least two fibre fractions having different fibre compositions， and the fractions generated are recovered and included in different layers of the same fibrous product. With the invention， it is possible to screen an initial material and form a product which has better properties than a corresponding product， the initial material pulp of which has only been refined.
