spool of vintage cotton cord, new old stock traverse rod drapery cord

Vintage cotton cord manufactured for traverse curtain rods, though we can think of a million DIY and craft projects for this stuff!

The spool measures about 5" tall x 4", it's not full, though there's a lot of cord here. We don't want to unwind this and risk kinks and tangles, so aren't measuring this, I'm sorry.
