The invention provides a splicing needle method for splicing and sewing double-sided fabrics, which comprises the following steps: preparing manual needles and sewing threads at the position to be spliced for an upper cutting piece and a lower cutting piece of two double-sided fabrics; on the longitudinal cutting section of the upper cutting piece, the first needle entry point of the manual needleis lifted for the first time, knots are tied at the first needle entry point, and the threads pass through the top surface of the upper cutting piece obliquely upwards from the first needle entry point of the upper cutting piece; starting from the first needle outlet point, the manual needle and the sewing thread obliquely downwards pass through the top surface and the longitudinal cutting section of the upper cutting piece towards the left side to carry out the second step of needle walking; starting from the second needle feeding point, the manual needle threads obliquely downwards on the bottom surface of the lower cutting piece and passes out from the bottom surface to carry out the fourth step of needle walking; then, keep the stitch size spacing to be uniform and consistent, and sequentially and alternately sewing until the end. The spliced seam is very flat, and the stitches are connected like a plurality of triangles, so that an uncomfortable feeling caused by the thickness ofthe seam is avoided.
