Felted i-cord

I made an I-cord for my felted bag, and it’s not quite long enough to knot the two ends together…so what I want to do is to butt up the ends together and sew them instead. What’s the best way to do this so that it is strong? TIA:muah:

Weave the yarn back and forth, even splitting plys and it should stay nice and strong. The fibers will kinda glue themselves to each other, making it sturdy.
Hope this helps, Mary
