I need to weave something at 28 ends per inch in 8/2 cotton. I have a good assortment of reeds, and would like to avoid reed marks. Which do you think will work better: Sleying 3-4 in an 8 dent reed or 2-2-3 in a 12 dent? I did something similar but in cottolin, using the 12 dent and did get reed marks which did not wash out, they weren't altogether objectionable though. Thoughts?
