[8D] hay yall i get most of my bow work done at the shop but the nock on my string is moving and the string needs to be re wraped i was wondering how to do it myself what do i need to know to do it right

Here's a pretty good diagram on how to serve your string. I suggest you get a good serving jig, and use the right serving material for the type of nock, and string, you have. Hope this helps. Be safe.
