Mason Jar Cozy – Free Pattern

IMG_7839

The mason jar – gotta love it for carrying coffee, tea, ice-water – you name it.   Since it’s glass, a mason jar is non-reactive (unlike plastic water bottles).   The screw-top lid keeps drinks from spilling in the car/in my backpack.  And they’re super convenient (I’ve got stacks of them in my cupboards).

I used to tie a dishtowel around my jar to catch condensation (on iced drinks) or help insulate (hot drinks).  I figured a knitted cozy would work much better than a towel, and, yes,  there are knitted jar cozies you can purchase online.   But buying one would take all the fun out of working out a pattern myself and doing some stash-busting/saving some pennies at the same time!

I wanted the cozy to 1) be made of wool to wick water and insulate well, 2) fit snugly, so it wouldn’t slouch and slump down, and 3)have a handle for carrying or attaching to a carabiner.

So, here’s the finished pattern to share with you (In two sizes – quart wide-mouth, and pint wide-mouth)!  You know the drill -please, don’t reproduce the pattern or use it for profit without my express permission, but feel free to knit oodles for yourself and as gifts (they are quick to make, taking less than a day!).

    This is a great idea – thanks for sharing! I think this would be a wonderful way to make hanging lanterns too – the handles might have to be longer (or possibly made of something not flammable) but wouldn’t it be pretty to have the light shining through the wool?!

  2. So handy and cute! Lovely to meet you.

  3. Joanne says:

    I love this idea but I can only crochet. Do you have a pattern for crocheting?
    thank you

  4. Amanda says:

    These are so cute! I would love to find a way to work these up in crochet as I am not quite comfortable doing more than a cast on in my knitting yet. (currently working on gloves from a not pattern just doing them amigurumi style.)
    I actually tracked you down for another question… found a comment on a “nosty” link (learning how to use one for my crocheting) about knitting & walking… I want to know what you mean when you “loop your ball onto a holder, then on to your belt loop” – Do you actually have a holder going thru the ball (like a HUGE caribeaner?)
    I walk & crochet all the time, but I am tired of holding the ball in the crook of my arm & I have not yet found a good long handled bag to put the yarn at waist height.
    THANKS!!!

  5. Angela says:

    Amanda – I’m not a crocheter, so sorry I can’t help much with that…

    as for knitting and walking – I wind the yarn into a self- pulling ball, and put a leather strap (or a big caribeaner or a loop of cotton yarn would work, too), and tie it to my beltloop. Or, I made several small drawstring bags, which I can put the ball/skein of yarn into, and tie it to my belt loop, a strap on a Ergo, etc, and knit and walk.

    Thanks for your comment!

  7. I wish my wrist would let me knit still! Dratted tendonitis.

    Have you considered making these out of wool, a bit too large, and then machine felting them? Just curious. I have a coffee-cup cozy that someone did that with, and it’s quite cool. And it would be really good for insulating cool or hot stuff, as it’s so tightly felted.

    Very cool. :)

  8. Angela says:

    Lisa – Thank for commenting! I have found that the Lamb’s Pride is so prone to felting, that just using it on the jar, holding it, etc, will result in it felting a fair amount and fitting tighter on the jars (esp if using cold drinks that sweat, since the wool wicks water off the jar and then handling it makes it felt.)

    Honestly, I never worked up a felted pattern b/c I have a Cabrio washer (a top-loader with NO agitator) and while it washes my clothes great, it can’t felt anything worth a darn! :)

    One question… what is knit 1 KFB? What is the KFB part?
    Thanks,

    Just curious – is there anywhere I can purchase a finished product? I am not crafty in the slightest, but have switched over to a mason jar for my travel cup and would love to have a handled cozy. These are exactly what I’ve been looking for!
