DIY Koozie

For this month’s Fat Quarter Tuesday project we thought it would be fun to learn how to create a custom Koozie! We even supplied a FREE printable sewing pattern for you to use when making your own! And, we added a PNG file for you to use in our creator tool so you can customize the fabric around it! Follow along below to see how to sew up your Koozie and how to use your free file in our creator tool!


  • 1 Fat Quarter Microfiber Polyester
  • 1 Fat Quarter Insul-Fleece Interfacing
  • Sewing Machine
  • Heavy Weight Embroidery Thread
  • Hand Needle
  • Scissors
  • Pins

Using the creator!

If you choose to use the creator to create your own Koozie save the .PNG koozie file to your computer. Then go to our creator tool online and start a new design by going to File –> New.

A dialog box will appear. Here you will enter in your repeat size. The full size of the koozie is 5” x 11.5”. So, enter that or larger then choose your background color and click apply.

Next, You will go to Add –> Image. Another dialog box will appear, and you will choose the Creator Koozie File you saved to your computer. The image will enter your workspace, but you will need to set the size of the design.

Click the gear in the left corner and enter 5” as width and 11.5” as height. Now your koozie is ready for decorating!

You can add more images from your computer, names clip art and more to completely customize your design. Also remember that one side will need to be rotated 90 degrees so that it is upside down when designing. Once the pattern is sewn that side will be folded upward keeping it right side up.

Keep in mind that you need 2 pattern pieces for both the inside and outside of the koozie. So, you can either have the same on the inside or create a coordinating inside pattern to go along with your outside design!

If you already have a fabric you would like to use you can print the free PDF sewing pattern to cut your pattern pieces out of any fabric. You will also need to either use this file or one of your fabric pattern pieces to cut out your insulation interfacing as well. We chose to use a design one of our amazing artists farijazz shared with us, Chinoiserie2 twigs, and had it printed on our microfiber polyester. We recommend this fabric for this project because it itself has a good weight and insulation.


Once you have your fabric and insulation pieces cut out and ready to go its time to start sewing!

First you will baste your insul-fleece to the wrong side of one of your pattern pieces at 1/8” seam allowance. Insul-fleece is a great material that helps insulate your beverage. It will reflect heat or cold back to its source. You can find this in fabric stores usually where you find your interfacing!

Next, you will then place your pattern pieces right sides together and pin leaving a 1-2” gap at one top of the ends. Sew around at ¼”.

Now trim and clip edges and turn your pattern right side out. You will then press under opening and top stitch both tops of pattern.

Now it is time to stitch the sides together. This is done by hand with a strong decorative stitch we chose a cross stitch with a contrasting thread.

All done! These koozies are easy to make and sew fun. They make great gifts or party favors!
