Through one of the casing openings that you left unsewn in the back seam, thread your cord through and out the other side.

Using a large safety pin on the end of your cord you can push (caterpillar) it through the casing and out the other side.



Pin both sides of the cord in place so it does not pull out in the next step.



Turn your hat to the center front of the casing, here you will be cutting a small slit, through only the top piece of fabric, NOT the entire way through.



Pull your cord out through the hole in front. while adjusting and repining the cords on the back at the casing openings. What we are doing here is getting the cord out the front of the hat, mostly for decorative purposes. If you wish for your cord to be on the back side at the seam omit this step and do not cut a hole in the front of the casing.



Once you have the cord adjusted and just the 'tails'' are hanging out the back seam, turn your hat inside out and sew the seam, on the casing, where we previously left un-stitched. This will close this small hole and catch the "tails" of the cord so it will not pull out and get lost!



Finally thread the cord through toggle and knot the ends so they don't pull through. Now you can adust and tighten the top of your hat!
