I use the stitch on my machine that sews 5 straight stitches, then one off to the side zigzag. It does a great job, thought because it's not a true blindstitch, I need to put the bulk of the garment under the arm, but that no big deal with most apparel. You fold the hem in such a way that the 5 stitches are in the hem and the needle picks 2 threads in the pant fabric as it swings over. Do you have a machine with any built in stitches or cams? This one is pretty common.
