I've done the neck - the usual process, and in the end I attached it with some hand backstitching. (Sleeves were backstitched as well.) I have chosen a pattern to complete it but I'm not sure yet.

If I do it, it'll be
the chained feather stitch from
Annie's vocab of stitches, outlined with two backstitch lines. I tried it and I didn't believe how nice it was ;)
