Old Thread - Ok or No?

Everyone has it - old thread. But do we want to use it?
It's certainly a question I think about when choosing thread from my stash.


variety of thread

Above are a few of all the threads I have stored away, anywhere from 2-15 years old - are they still good? And how do I find out??

First, there are several factors that affect the lifespan of thread: light, humidity, and dust.


Light:

We all know what light does to quilts over time. Well, the same happens to thread, not only fading it, but weakening it.


Humidity:

Low humidity makes for dry, brittle thread. And high humidity invites mold.


Dust:

We all have it, no matter how clean we keep out space. Unfortunately, on thread, it's hard to remove. It too, can dry out the thread, and cause further lint buildup in your machine.


Storage:

The first step for keeping thread is to store it properly - out of light sources, in an even temperature and humid area, covered to be free from dust.


Testing:

Once all of the above conditions are met, how do I tell if questionable thread is still good? The best way is to unwind a bit and pull on it, trying to break it. If it snaps easily, then it's old, and should be saved for projects that DO NOT require thread for strength, such as basting, tacking, and other temporary hold projects. 

But what if you really don't want to part with that big, full spool? Then unwind a few layers, going up and down the spool, until a fresher layer of thread is exposed. Try the pull/break test again. Does it break now? It's up to you and your project as to whether the thread is usable. I personally have found that deeper down into the thread layers, the thread is fine.

But if you're totally unsure, then commit it to basting thread, or bite the bullet and toss it!

Happy Quilting!

  1. Now you have me thinking, my thread is on spools on the wall, maybe it wasn't such a good purchase, although much are neutrals and have regular use. I went through my threads a few months ago and binned all the old ones, the ones I don't like and I will never use. I only buy brands I love now but I think I will look out new storage for coloured threads I won't use often. A useful and informative post Susan, thank you.

    1. You are so welcome! I certainly pause and think about how old the spool is before I use it. And I do have those that are set aside for non-important stuff. Unfortunately, that bin is starting to grow!!

  2. I have a big open cabinet on the wall that I have my Gutermann small spools stored in - 100 spools on the wall - it is a cabinet like some they have in the stores. I got it years ago - maybe 15? I know there are some colors I rarely use and others that I have replaced time and again - I love this thread for my applique - so far they all see to be ok the rest of the thread is stored in plastic boxes with lids

    1. Sounds like you have a pretty good storage system going! Maybe replace those seldom used with extras of the favorite ones - but don't go overboard!

  3. Hi Susan,
    Great post and food for thought. I keep all of my thread in a plastic box, like a pencil box the kiddos use in school. I have recently transitioned to spools of Aurifil and those are used frequently. ~smile~ Roseanne

    1. Thanks Nanette! Hmm, maybe we'll have to start writing the date of purchase on the spools, just like my mom did for canned goods. Then we'll really know thread age.

  6. I have thread from my grandmother. I rarely use it, and not on good quilts. If I do think about using it, I do the "tug test". Usually this thread is in a big jar, where it's colorful, pretty, and reminds me of her :-)

    1. How wonderful! I'd keep it for the sentimental and viewing pleasure it brings!

  7. This is a good subject to talk about, and apply to our own sewing studios. I've noticed a difference with radiant heat in the floor below the one I work on vs. forced air and heat in my last space. Now I have windows and beautiful northwestern light, but have noticed a bit of color change in a few fabrics. If our thread is compromised, our fabric fiber is also. We should absolutely be careful of how both are stored. Thanks for talking us through it, Susan.

    1. Definitely a subject that needs constant attention. Heat and light make a big difference, affecting all threads and fibers. I store threads and fabric covered and away from light sources. Whenever I see studio makeovers with the fabric beautifully displayed on shelving, I cringe - those folds are prime fading spots. And not only is folded fabric ripe for fading, but so are any quilts left out where sun can get on them. I have a wall hanging under a sky light, which I should put UV protective spray on.- just haven't had time to get to the store.
      Hopefully this post will get everyone thinking about storing their hard earned quilt materials.

  8. These are great tips and exactly how I approach using older thread. Great share!
