Weave one end of the ear tail into a yarn needle and then into the marked stitch (stitch 5).
Weave the other end into the yarn needle and then into the next marked stitch (stitch 6).
Make a double knot on the inside of the head but make sure to leave a bit of yarn hanging down before you make the knot. This helps the ear lay nicely.
Cut off any excess yarn from the knot and repeat for stitch 13 and stitch 14.
