If I was to do one again, I would do the head and body rectangle out of one piece of fabric so that the bottom bottom edge could be sewn by machine to the fold. This way the whole body and face would be secured before you sew the side seams up. You could then hand sew across the neck and not worry about the head pulling out after some tough love. I sewed across the neck edge from side seam to side seam with 6 strands of embroider floss to secure it.
