Crochet Mug Cozy
Thank you to A Little Glitz for the inspiration for this Mug Cozy. While testing my Santa Mug Can Cozy pattern, Michele suggested it would also be great for St. Patrick’s Day so I redesigned the pattern and here it is!
This St. Patrick’s Day Mug Cozy Crochet Pattern is written in English for right-handed crochet using standard US crochet terminology. If you’re more familiar with UK terminology, check out my US to UK Conversion Chart.
St. Patrick’s Day Crochet Mug Cozy Pattern Details
Finished St. Patrick’s Day Mug Cozy (using the yarn listed below and a G/6 (4.00mm) hook) is: 10.25″ long and 3.5″ high.
It is designed to fit the following size mugs:
- Circumference (all around the center of the mug): 10 1/8″ – 10.5″
- Height (from top to bottom): 3.75″ – 4.5″
- Width (measuring from end to end across the bottom): 3.25″ – 3.5″
Instructions for adjusting the sizing to fit a smaller or larger mug are included below.
4″ x 4″ (10 cm x 10 cm) = 13 sc and 16 rows
Yarn: Any size 4 (medium) yarn.
I used Loops & Threads Impeccable Yarn, Solid. This yarn is medium (4) weight and 100% acrylic. The size is 4.5 oz / 127.5 g. A skein is 285 yd./260m and you only need less than a quarter skein in total.
I used the color “Kelly Green” for the main part of the mug cozy; the color “Black” for the belt; and the color “Sunny Day” for the belt buckle.
Crochet Hook Size: G/6 (4.00mm) for everything but the belt buckle. For the belt buckle: F/5 (3.75mm).
Other Materials: Yarn Needle, Scissors, 1.5 cm Black Button, Black Thread, Sewing Needle, Measuring Tape and a Mug
Optional: You may find that you would like to add an extra strap and button at the bottom of your completed mug cozy. If you do this, you will need a second 1.5 cm black button.
st = stitch
sts = stitches
ch = chain
sc = single crochet
dc = double crochet
sl st = slip stitch
Crochet Mug Cozy Pattern Notes
- The St. Patrick’s Day Mug Cozy is worked flat.
- Each row has 35 stitches.
- Ch 1 does not count as a stitch.
- Always start in the same stitch as the chain.

Ensuring Proper Sizing
Before you begin the pattern, measure your mug. (If you don’t have one you can follow the pattern, which should fit a standard size mug).
Finished St. Patrick’s Day Mug Cozy (using the yarn listed above and a G/6 (4.00mm) hook) is: 10.25″ long and 3.5″ high.
Measure Your Mug’s Circumference:
If your mug’s circumference (all around the mug) is between 10 1/8″ – 10.5″, follow the pattern.
If it is larger or smaller, increase or decrease the number of chains + 1. For reference, 36 chains creates a row of 35 single crochet stitches that (once a few rows are completed) is 10.25″ long.
Measure Your Mug’s Height:
If your mug’s height (from top to bottom) is between 3.75″ – 4.5″, follow the pattern.
If it is larger or smaller, you will need to increase or decrease the number of rows. For reference, the chain row and then 14 rows of the pattern creates a finished item that is 3.5″ high.
Measure Your Mug’s Width:
If your mug’s width (from end to end across the bottom) is between 3.25″ – 3.5″, follow the pattern.
If it’s width is larger or smaller, when you make the button strap/loop after row 8, increase or decrease the number of chains on the button strap/loop. For reference, the button strap with 8 chains fits a mug that is between 3.25″ – 3.5” wide.

St. Patrick’s Day Mug Cozy Pattern Written Instructions
Crochet Mug Cozy
With green colored yarn and a G/6 (4.00 mm) hook, ch 36.
Row 1: Note: you will be working each stitch of Row 1 into the top loop of each chain. This is important as we will be attaching the brim later on in the pattern to the bottom loops.
In the 2nd ch from hook, sc into the top loop. sc into the top loops of each ch across. (This row and all rows have 35 sts in total)
Row 2: ch 1 and turn. sc in the next 34 sts. On the final st, change colors: still working with your green yarn, insert your hook into the last st, yarn over and pull through green yarn. You will now have two green loops on your hook. Add black yarn to your hook and pull the black yarn through the two green loops. The completed sc stitch should be green but your black yarn will now be on your hook ready to be used.
Fasten off green yarn, leaving a tail to weave in ends.
Row 3 (Belt): with your black yarn that is now on your hook, ch 1 and turn. sc in each st across.
Row 4 (Belt): ch 1 and turn. sc in each st across.
Row 5 (Belt): ch 1 and turn. sc in the next 34 sts. On the final st, change colors: still working with your black yarn, insert your hook into the last st, yarn over and pull through black yarn. You will now have two black loops on your hook. Add green yarn to your hook and pull the green yarn through the two black loops. The completed sc stitch should be black but your green yarn will now be on your hook ready to be used.
Fasten off black yarn, leaving a tail to weave in ends.
*Measure work: it should measure 10.25″ long. If your work is much longer or shorter, I recommend starting again with a larger or smaller hook size.*
Row 6: With your green yarn that is now on your hook, ch 1 and turn. sc in each st across.
Rows 7 & 8: ch 1 and turn. sc in each st across.
Row 9: ch 8 (to create the button strap) and turn. sc in each st across.
Rows 10 – 14: ch 1 and turn. sc in each st across.
*Please note that you may find 14 rows too many depending on your mug height and yarn weight. Best to test out the cozy on your mug as you get close to the end and stop when your mug cozy is the height you would like.*
Fasten off and weave in all loose ends.
With the front of the mug cozy facing up, position it so that the belt is at the top, furthest away from you. (The button strap will be on the left side)
Remember how we worked Row 1 into the top loops of each chain stitch? We will now be working into the bottom loops of each chain of your now completed mug cozy.
Starting in the first chain (on the top right), attach green yarn to the bottom loop. Ch 2. In same st, dc. In the next bottom loop, dc. In the next bottom loop, 2 dc in same st. Repeat *dc in next bottom loop. 2 dc in next bottom loop.* from * to * across. (52 dc made, plus the ch 2 that began the row). Fasten off and weave in loose ends.
With F/5 (3.75mm) hook and golden yellow colored yarn, ch 18.
The rest of the belt buckle is made in one continuous row.
1st Rectangle Side (short): In 2nd ch from hook, sl st into back ridge loop. In next 2 chains, sl st into back ridge loop. In next ch, sl st x 3 into same back ridge loop.
2nd Rectangle Side (long): sl st into next 4 back ridge loops. In next ch, sl st x 3 into same back ridge loop.
3rd Rectangle Side (short): sl st into next 3 back ridge loops. In next ch, sl st x 3 into same back ridge loop.
4th Rectangle Side (long): sl st into next 4 back ridge loops. sl st into 1st sl st to join.
Fasten off leaving a 12″ tail. Weave in the first end to belt buckle. Using a yarn needle, attach belt buckle with the rows of black in the middle. I placed it so that it would be facing you when holding the right handle but you could place it in the center of the mug (or make two buckles and put one on each side!)
Test out the mug cozy on your mug to ensure proper button placement before sewing it on.
Sew on button on the opposite end from the button strap between rows 9 & 10 with black thread. Place button approximately 0.5″ away from end (placement spot may change depending on your work and size of mug, ensure strap fits over the button before sewing)
Optional Extra Strap and Button
You may find that you would like to add an extra strap and button near the bottom. To make another strap, attach either green or black yarn (depending on where you would like the strap) with a sl st and ch 8. Sl st to join the chain and weave in ends. Sew on button on the opposite side.
And now you have a St. Paddy’s Day mug!
