I use one strand of good quality thread for hand sewing binding. I do the lock stitch thing so the thread doesn't pull out of the eye and have about an arm length piece for sewing. Every stitch you make twists the thread so after sewing for a bit, hang your work upside down to let the thread unwind. This prevents it from doubling back on itself. I have never had to "dress" my thread but some people like a little sewing wax on their thread.
