Make the french braid first. I did a diagonal inside-out french braid. A regular french braid would also work. Or if you don't know how to french braid, you could do an elastic braid. Whatever!
To sew around the braid, I used our plastic needle and did it basically the same way I did this ribbon headband hairstyle. Start sewing at the bottom, on one side of the braid. Sew up to the top and down the other side with each ribbon. (You'll need 3 pieces of ribbon total.)
Have a happy St. Patrick's Day! Oh, and in case you're wondering, the cute shamrock bow came from Kells Bows.
