I'm graduating from a warping board to a warping mill. Using the mill should be straightforward, but one question. Do I not overlap warp threads on the mill, just like you wouldn't overlap on a warping board? In other words, I don't want to pile threads on top of threads, and all threads should sit next to another thread, not on top of others. Is this correct? I've watched some videos about using a mill, but none address this question.
