As someone who just lost power in an ice storm for 4 days without a working fireplace, I’d say keep it. Better to have and not need, than need and not have.

This was one of the few shows I’ve ever talked my parents into watching and it became one of my dad’s favorites. Ray Wise as the devil and the dmv as a portal to hell, just fantastic. He still mentions it sometimes.

You could start with a known quantity of thread. The starting known quantity could be measured out on a swift or niddy noddy or warping board/reel. Then wind on to your spool and then count/measure the remainder. If you want to know the number of turns required to fill a certain amount, you can count as you go.

Also they do make yarn counters, but whether it would work for this would depend on the thickness and material of the thread.
