I’m making a rep runner using 8/2 unmercerized cotton for the warp and for the weft, the 8/2 for the thin and 8/16 unmercerized for the thick and to get the width I wanted, I ended up with over 900 ends. Because I've been warned that the 8/2 unmercerized cotton can be stickier than mercerized and because there are so many ends, I'm spreading the ends over 6 of the 8 shafts on my Spring 2 countermarch loom
But I'm stuck on the tie up for a 2 block 6 shaft rep weave.
Should I just use 2 treadles with 1,3,5 on one and 2,4,6 on the other or would it be better if I used more than the two treadles in which case, how would I do the tie-up?

I'm curious, what sett are you planning to use? And, just my personal experience with 8/2 cotton - I've used it as warp and/or weft for about 30 years and can't remember a time when 8/2 cotton shredded or let me down in any way.....

Morning Sandra,
Thanks so much for responding, and so quickly!
I’m using a sett of 48 epi. And I’m not worried about it shredding, but being sticky and, with such a close sett, having difficulty getting the shafts to rise as the threads find a way past one another and this of getting a clean shed.
