I've looked over my notes but I'm having trouble locating what the limits were to using two sets of lease sticks.
I was thinking of winding two warps for two sets of colors so I wouldn't have to cut and retie repetitively but I can't recall if there is an issue if one warp has far fewer ends than the main warp.
Hope this makes sense.
Hi Nato - you might find what you are looking for in Season 7 Episode 1 where Jane talks about and demonstrates using 4 lease sticks for two different sections of the warp she is putting on for Turned Twill. Check it out here 7.1.4 - A Warping Discussion
7.1.4 - A Warping Discussion - hope this helps.......
