What a wonderful rabbit hole to go down. My takeaways are it could possibly be used for knitting, but traditional spool knitting that the Grandma uses in the video doesn't show up in history until the 1500s. If the Romans did use it for gloves then knitting has been around much longer than we have evidence of or they were using a different method with the dodecahedron.
