lot vintage pink and green cotton rug thread, carpet warp weaving cord

Lot of vintage cotton rug warp (a string-like yarn, probably Maysville?), in flower pink (four 4" tall spools) and green (three 4" tall spools). This works well as a sturdy crochet cotton, too, nice for net shopping bags and totes.

These have been stored away for many years, and the outer wraps are very discolored and dusty. The thread is very strong and supple, though.
