Lay the fabric flat and place the collar template on top.
Pin the template in place and cut out, leaving a 1" excess around the sides.
Fold the edges over by 1/2", then another 1/2", pin and sew in place with white thread.
Pin a length of blue ribbon along the back of the collar, about 2" from the bottom.
Stitch in place with blue thread.
Pin a length of blue ribbon around the outside edge of the entire collar, about 1/2" in from the edge, leaving a long tail at either side so that you can tie a bow in the middle of the collar. Sew in place.
Tie the two tails into a bow and your collar is ready to wear!
