I love making these baby blankets. They are SO easy! Takes about 2 hours to make one. I use 1 1/4 yards of flannel for each side. With wrong sides together, I pin all the way around and then trace around a 9" paper plate to round the corners. I then sew a 1 1/2" seam all the way around. Then I fringe all the way around by cutting almost to the seam. I then take floss and "tie" it like you would a quilt.
I've obviously not washed these yet, but the more you wash them the more "raggy" the edges will look.
You could make a couple of burp cloths to match and it would make a great baby gift.
