Back Seam
Use the longer thread tail to stitch part of way up back seam, about 3 cm (slightly more than an inch) but no more (red dotted line); you'll need to leave an opening to stuff the body later.
I usually stitch back a couple stitches here to keep the seam together.
If there's thread left over, just leave it, you can use it to stitch up the stuffing hole later.
