Mason Jar Cozies {Hello Summer}


There’s something about summertime that makes me want to drink out of a mason jar.

Okay, actually I like drinking out of mason jars all the time…


But the drinks that I drink most in summertime…Arnold Palmers…cherry limeade…ice tea…lemonade…plain old H2O…look especially cute with a straw and in mason jars.

I thought a useful {and colorful!} way to keep my favorite summertime drinks cold would be to whip up some quick cozies.


This is the simplest of sewing.

If you can sew a straight line, you can make one! I bet it won’t even take you longer than 20 minutes…


What you’ll need:

sewing machine and basic supplies {a walking foot is helpful if you have one, but not necessary}

2 pieces of fabric, 12.5 in x 3.5 in {scraps or fat quarters are perfect!}

1 piece of insulated batting {regular batting or fusible fleece would also work, but wouldn’t insulate as well :)}, 12.5 in x 3.5 in

2 in piece of sew on Velcro {the adhesive kind will make your machine mad if you try to sew through it}


Start by collecting your materials and cutting them to size.


Then pin your fabric and batting.

The order and direction of the fabric is important!

Layer and pin…

insulated batting

fabric, right side up

fabric, right side down

When pinning, leave a 3-4 inch gap for turning later on.


Sew around the edge, using a 1/2 inch seam and carefully pivoting at each corner.

Don’t forget to leave an opening, and back stitch at each end!


After sewing, remove any pins and carefully clip all four corners.

Be careful not to cut too close to the stitching!


Turn the cozy right side out, using a knitting needle to carefully push out the corners, and press.

Be sure to fold in the opening so its seam matches the rest of the stitching!


After pressing, top stitch a 1/4 inch seam around the entire cozy.

Make sure the opening is sewn shut.


When the top stitching is complete, pin the Velcro pieces.

Pin one to the front of the cozy and one to the back of the cozy so it closes properly around the jar. {Practice wrapping it around the jar for a good fit if you need to!}


Then carefully sew, as close to the edges as possible, around each piece of Velcro.


Trim any loose threads and you’re done.

Time to enjoy a nice, cold summer drink with your cute new cozy!

  1. Oops, sorry bout my first “non comment”!!

    I love this project and am going to make some today. I was planning on using mason jars for drinks at our 4th of July party, so this will be perfect.
    BTW I already follow Cheryl’s blog, she is awesome 🙂

  2. I love these! Drinking out of a mason jar is so cool. Is the insulated batting the same type that is used in making pot holders…with the silvery side?

  3. I had to add 2 inches to the length to get this cozie to wrap around a pint mason jar, but otherwise, very easy directions & a wonderful idea! Thank you for sharing.

  4. My daughter just sent this to me this morning,we are going to try and make some. We will let you know how they turn out. Thanks for the idea.

  5. Having some trouble getting the corners pushed out all the way, maybe the fabric should be a little longer than the batting?

  6. having a little trouble getting the corners pushed out all the way, maybe the fabric should be a little longer than the batting? I’ve just made the one, but could probably add an inch or two to fit it around the pint size jar

  7. I love this pattern thank you for sharing. I made some for Christmas last year and now I’m gonna make some more ! I’m super excited !
