DIY Mug Cozy with Insulated Lining - Tutorial at

I always need a cup of coffee to start my day. But sometimes, I’m too busy and end up with half a mug of lukewarm coffee after forgetting to drink it. For those days, I decided to create a little something extra to keep my coffee warm enough to drink when I finally get a chance. Now, I can get distracted, and still come back to a piping hot mug of my favorite morning pick-me-up. Perfect for those busy days when you need all the caffeine you can get.

What You Need:

What to Do:

Cut Fabric

Measure your mug and cut the fabric and batting to fit. The length of your fabric should be about an inch and a half shorter than the circumference and about an inch shorter than the height. I used a typical sized mug, and the dimensions were 9 x 3 1/2 inches.

Sew together

Pin all of the pieces together and sew around the edge about 1/4 inch in. Once it’s all sewn together, add your bias tape. The way you want to sew it on is entirely up to your own preferences and skill level. For more information about sewing on bias tape, and how to create neat corners, Prudent Baby has a few fantastic tutorials.

Tuck Elastic

Flip Elastic

Once you get to one of the short sides of your cozy, insert the elastic cording in a loop under the bias tape and fold it up before sewing the edge. Pin the elastic down.

Sew Elastic

Sew the tape on normally, but go back and forth over the elastic a few times for reinforcement.

Finished Sewing

Continue around the edge of the cozy and pull it out of the machine.

Attach a button onto the cozy on the opposite side from the elastic. I made sure the edge of the button was even with the edge of the bias tape.

Add your cozy to your mug by threading the elastic through the mug handle and around the button. Enjoy your coffee when you get a break!
