I've heard not to use "old" thread. I've bought thread "new" at stores and it unravels, leaves a lot of lint, doesn't sew right or breaks continuously. (Yes, I had it threaded correctly.) And I don't buy inexpensive thread.
As soon as I changed the tread, my machine (a Baby Lock) worked perfectly. This could have been the same color, same thread, bought at the same time! When I put the "bad" spool back on, same problems.
How can you tell if thread is too old (or just bad)? How old is too old?
After some rough experiences with old thread, I pretty much throw away any that I've not purchased. Unless it's on a wooden spool, then I keep it for the heck of it----------in a big glass jar.
I've had some from stores that closed 20-30 years ago. I had one spool marked 5 cents. It was on a wooden spool, so I kept it. But THAT had to be old.
