You could do it every new stringer does. I found that weaving just one ahead makes it easier to weave especially near the top or when no crosses are tensioned. When you get past that the weaving is still pretty easy but when you go to pull the crosses through the main the loops are never long enough and it is much harder to fan the strings as you pull them through. The farther up and down the mains you can fan the crosses the less wear and tear there is on the strings.
I have the ability to drive people crazy, not sure if I was born with it or I learned it but I'm damn good at it.
