What is the purpose of a Crochet Mug Cozy?

This crochet mug cozy helps to keep your drink warm and prevents you from burning your fingers. As a bonus, this crochet mug cozy pattern has a built-in coaster on the bottom which protects the surface you place your mug on as well. Think of it as a pretty way to insulate your hot drinks.

What is the best yarn for crochet cup cozy?

Both cotton yarn and acrylic yarn work well for cup and mug cozies.  Some folks worry that the heat from the coffee will melt acrylic yarn but you’d have to have a SUPER hot coffee for that to happen. I’ve made dozens of mug and cup cozies with acrylic yarn and never had an issue.

I prefer using cotton just because it doesn’t usually get a halo like many acrylic yarns do.  No one likes little fuzzies in their mouth when taking a sip of coffee – yuck!

I used WeCrochet’s Dishie cotton yarn for this mug cozy design because it has great stitch definition and has a great range of different colors to choose from.  Plus, it looks great, wash after wash.

How long does it take to crochet a cup cozy?

To make this easy mug cozy, it takes me on average about 30 – 45 minutes to make one in the written size below.

  • Gauge is vital to ensuring that the project fits as expected.  By not matching gauge, it will affect the size of your finished mug cozy and the amount of yarn used.

 FO and weave in ends.


To get the ideal placement for your button, put the mug cozy onto a mug and pull the buttonhole loop over the top of the handle to the other side of the cozy.  Use either a length of yarn or a sewing needle and thread to sew the button to that spot. FO and weave in ends.

Adjusting the Size of This Mug Cozy for a Larger Cup:

Follow instructions for Rounds 1 – 7 and then continue to increase by 6 STs/Round until the Base is the same size as (or slightly smaller than) the bottom of your mug.  

Here are the next few rounds of increases written out to help you get started:

SC 3, SCINC, (SC 6, SCINC) X 5, SC 3. (48)

SC 7, SCINC) x 6. (54)

SC 4, SCINC, (SC 8, SCINC) X 5, SC 4. (60)

(SC 9, SCINC) x 6. (66)

Once your base is the appropriate size follow the instructions for Row 8 and repeat the (SC, DC), SK 1 ST pattern until there are 2 STs left.  SC in 2nd to last stitch, leave the last ST unworked. For a wider handle, leave more STs unworked. 

Repeat Row 9 until cozy is approximately half an inch from the top of the mug, ending on a RS row.

Create your buttonhole loop, per the above instruction, slip stitching into the last ST of the last row you worked and the end of the row below. Sew your button to the front of the cozy.
