How to put strips together for rag rugs

I spent all this time sewing my strips together for my rag rugs. Which worked well, but of course I had to have a sewing machine. Found a new way to put them together in an old Handwoven magazine. Cut a slit in the end of two strips. I have been putting it horizontal to the length, but I might try putting it vertical and see how that works. Anyway, put one fabric strip inside the other through the slit, then loop the fabric through. It works pretty great because I can make a nice length anywhere. No sewing machine required.
