When should you throw out thread?

If you have a stash of very old threads and you’re not sure if they’re still good to use, take a small sample (approx. 6-12”) and try pulling it apart. If you get a clean break, the thread is still good to use. If it shreds or pulls apart like a cotton ball would, then it’s best to throw it out.

How can you tell if an old thread is good?

Because cotton is a natural fiber, it will degrade over time.

If the thread snaps (you should feel a nice, crisp break), then it is OK to use.
