Yes, you have a coat--but.... There are several very simple solutions for this also.
Sewing a decorative border
If you choose to glue, I suggest fabri-tac glue used in a well ventilated area. If you sew it on, I suggest a long zigzag stitch to tack the cord.
As you can tell, this is the option I went with. My machine has only one decorative stitch, and that's a zigzag, so I opted to hand stitch. If I had to do it over again, I would have gone with a thinner yarn, but the whole process took no more than an hour. I used a circular upholstery needle with a large eye.
I used the circular upholstery needle because when sewing with thicker fabrics, you need to apply greater pressure to the needle. With a straight needle, the pressure needed to go through the fabric has, believe it or not, caused the needle eye to go through my finger. Yes, this can be prevented by using a thimble, but then you're spearing the thing out the other end, ready to pierce through knees, elbows and other unsuspecting extremities.
The circular needle allows you to control the force and direction of the needle point a little better. The blanket stitch is simple and an good skill to learn, as its use pops up in a number of crafts.
There is a helpful youtube instructional video, and I also included a wikihow link on "How to do a blanket stitch." http://www.wikihow.com/Sew-Blanket-Stitch
You will notice the length of my vertical stitch is longer than both demonstrations. Length is up to you, but don't go longer than an inch. Long or short for the vertical stitch, you will not want to go any longer than 1/2" or 3/4" for the horizontal stitch.
Thank you for joining me today, next week we will sew a winter coat with upholstery fabric using pattern B 5093 This coat took a little longer to make, about two hours from cutting to finish, but, it can be done in half a day, even for the most deliberate sewer.
