Cable chain stitch: How to continue with a new thread

Today I stitched my first new row in cable chain stitch, the TAST stitch for week 25. When I was halfway I had to start a new thread. This is how I did it. First I started a new thread and came up where the last stitch with the old thread is going to end.

Then I continued with the old thread. I put it around the new thread from top to bottom to form the chain.

I made the knot like a normal cable chain stitch and took the needle to the back.

Then I pulled the old thread through, holding the new thread tight.

I stitched a few cable chain stitches with my new thread before I secured the old thread at the back. That way it's possible to change the look of the last stitch if necessary.

I hope this little trick is helpful for some of you.
