Yes, I have put my thread in the freezer. It works. The thread becomes dry and putting the thread in the freezer rehydrates it. You might want to give it a try.

I'm going to try it. It sounds reasonable. I just wondered if anyone had actually done it. Thanks!! Now, I just gotta make room.

I've used Sewers Helper, which is Silicone...but I cannot say it helps that much. Maybe I will try the mineral oil next time.

Well my son had me put a hard drive for my computer in the freezer so that I could get info off of it and we put paintbrushes in the freezer to keep them from drying out in between painting so why not thread.

I have not done this, but I have heard it before. I guess it would not hurt to try it!

I have put my thread in the freezer and found that it did indeed help with breakage.

Wow!!! What a great tip! When my thread breaks, I throw it away because I assume it has dry-rotted.

Old cotton Thread does dry rot - is the breakage being discussed new cotton thread? I don't think I would want to sew with "reconstituted" thread - we put too much work into a quilt. I wouldn't want to have my seams come apart on a quilt that only gets displayed, and rarely would find itself washed and dried.

I too have put the thread in the freezer. It did seem to help. I had assumed it was due to the sweating we see when we take things out of the freezer that rehydrated it. Never heard of the white mineral oil. Worth a try if you are going to pitch it out anyway....Just use on practice fabric first to check it out.

Are you using the right needle for that particular thread? Incorrect needles are the most common cause of thread breakage, not dryness...especially if your thread passes the tug test, meaning it does not break when you pull on it.
