I think knitting is supported by "They have been found across a northwestern swath of the former Roman Empire from Hungary to northern England, but not in other Roman territories such as Italy, Spain, North Africa, or the Middle East." as these are lifestock producing cold regions (and back then were more colder and swampy than today) where probably knitted wool was used instead of the textile that was used in the warmer regions where agriculture produced source fiber for the textile.
