A flat overedge seam joining together the edge portions of two superimposed fabric layers, such as are present at the toe of knitted hosiery, is formed with a looper-type sewing machine having three needles two of which form two separate series of loops spaced from the edge and a third of which forms a series of loops at a raw edge formed by trimming away an edge portion of the layers just prior to stitching.
