Permanent.
Effect
Pays out to 1,000 feet and lies where it is laid. It cannot be cut or broken by anyone but the holder. A steady pull winds it back in, gathering it around corners and through gaps, and while any thread is out the spool tugs the holder's hand toward the way back.
About
Waxed grey thread on a wooden spool, heavier in the hand than the thread on it accounts for.
