O.k here is a bit of a challange for someone maybe. Me and my lady friend has been debating, how old some wooden spools of thread she has acquired. Where is one to look for how to date a spool of thread? Many look real old, she thinks spool of thread was disconinued in the 30's or so. Me well I just don't know, looked abit on the net, but then she thinks maybe someone here may know a bit. So how do we date a spool of Thread???
