Winding long warps (more than 3 yards long) can be simplified by winding the warp vertically on the warping board. Some of us (i.e. Katzy) have been frustrated in the past with winding long warps and getting to the step of tying the choke ties only to bend down and discover that there is a missed pass on the lower levels of the warping board; resulting in a few threads that are shorter than the whole rest of the warp. Because Lunatics usually warp back to front, this makes a mess out of the warp when tying on to the back beam.
Path is Clear
When you wind the warp vertically, you can see the warp path clearly from the beginning where the threading cross is, all the way to the end where the raddle cross is and not have any more nasty surprises when you have completed the warp winding. I wouldn’t wind warps any other way now.
No More Aching Shoulder
The added benefit to winding the warp vertically is that you can just step sideways a couple times as you go across the board, and as a result, your arm and shoulder no longer get tired. When you spend a couple hours winding a warp, the benefit of keeping your shoulder happy can make the warping process so much more pleasant.
Of course, there are a few tricks to this: (1) make sure you keep a light tension on the warp so the pegs don’t bend in (you need to do this anyway so the left and right sides of your warp are the same length); and (2) wrapping a rubber band around each peg will prevent the warp from sliding off. Using rubber bands around the pegs also works as a great way to mark the path of your warp so that you can wind a second warp the same length as the first.
Warping Vertically changed my life and made the trips to the warping board much more enjoyable.
