Winding my own warp.

And it's going to be as long as can be. And I'm going to try and save time by tying (what a difficult word that is to spell - I had to use a dictionary) it on to the remains of the old warp from my last project, which is still threaded through the heddles. I shall re-sley it, however, as I want it to be a different sett. I wonder if it will work?
