How to finish an open edge with the invisible fasten off

For amigurumi pieces that'll be sewn onto another piece butย with the edge still visible, thereโ€™s a slightly smoother way to finish the piece. Like the regular fasten off, once youโ€™ve finished your last stitch, cut the yarn to make a tail. Remember to leave a tail long enough so that you can use it to sew this open piece onto another piece.
