I also like the birthing method. After turning, I generally do a decorative stitch along the outside edge and stitch about a 10 inch square in the middle to hold them together.
I have also done them where you sew the 2 pieces together with wrong sides together. Sew a good 1/2 to 1 inch around the entire blanket and then snip every 1/4 to 1/2 inch around to make a fringe. When washed, it frays and looks really cute. Very easy and simple.
