Question about Mobius

When you knit the rectangle and you’ve bound off, you then turn one end and sew it to the other. I’ve seen this with Kitchner stitch in a pattern. However, when I’ve looked at the Kitchner stitch, it shows stitches on both needles. How would you do that when the ends of the rectangle are end stitches? Is there another way to sew together a mobius? Thanks in advance.

If you do a regular Cast on instead of a provisional (temporary cast on, you would bind off the end and sew them together.
