I am threading an 8-shaft turned twill for tea towels and forgot to factor in my floating selvedges. I prefer to have them wound on the back beam rather than separately weighted. Can I just take that 1st thread in the line up and turn that into a floating selvedge? My draft would start on shaft 2 and end on 7 if I repurposed the first and last threads. Will that create any problems for me? Thanks in advance!!!
