Winding on the warp
I feel sort of silly asking this question...oh well here goes.
My instructor taught us that when you are winding the warp onto the warp beam you need to put something like paper or cardboard in between the yarns so that the they don't touch around each other. Is this a necessary step? Does it cause them to break from friction if they aren't separated by something? Again, I feel like I should know this already...But I thought I'd ask anyway.
