judging by the pictures, what I'm seeing is that she folded squares into triangles with stuffing in the middle and sewed around the edges using a small crochet thread with the blanket stitch and leaving a thread tail long enough to join the triangles. I believe she then used the tails to crocheted the triangles just catching the outer part of the blanket stitches to join the triangles together, probably tying one thread to the other as she went along or knotting them in the points some how. I can't see them that well, so this part is only a rough guess.
I'm not sure I'm correct but this is what I can see in those pictures (or my imagination).
