How do you re-weave a “broken” handwoven Navajo rug?

I googled this post title in many different configurations, hoping to get an answer.  Many of the choices were for ads wanting you to visit “XYZ Oriental Rugs” to purchase a rug or have their staff re-weave your carpet.  Some of the searches revealed how to re-sew a broken braided rag rug.  But two of the best solutions were from “rug chick” and “Mr. Fix-it.”  They recommended glueing the rug back together or duct-taping it on the reverse side.

Finding a match for re-weaving a Navajo rug

I gathered some home-spun wool yarns, as well as a couple of thicker cotton yarns.  You may see a match in the photo, but each was a shade off.  This won’t be easy to repair, since the warp threads–which appear to be cotton–are thin and broken (see below).

Since I didn’t find an answer to my question on the internet, I plan to find a large needle and some strong cotton thread and give it a go on my own.  If it works and looks decent, maybe I will make my own You-tube video on how to re-weave a handwoven rug.
