Materials Needed

Before we begin, let's gather our supplies. This project uses simple, readily available materials:

Yarn

• Worsted weight cotton or cotton-blend yarn in three colors:
  • Orange: approximately 50g (for the pumpkin body)
  • Green: approximately 20g (for the leaves)
  • Brown: approximately 10g (for the stem)

Pro tip: Cotton yarn works beautifully for this project because it's durable, washable, and has excellent stitch definition. The slight stiffness of cotton helps the koozie hold its pumpkin shape. Look for a rich, deep orange with subtle tonal variations for that perfect harvest look.

Needles and Tools

• US 5 (3.75 mm) knitting needles—straight or circular, whichever you prefer
• Tapestry needle for seaming and weaving in ends
• Scissors
• Stitch markers (optional, but helpful)

Gauge

22 stitches and 30 rows = 4 inches in stockinette stitch

Taking a moment to check your gauge is always worth it. If your gauge is off, your koozie might be too tight or too loose for your favorite beverage container. Knit a small swatch first, and adjust your needle size if needed.

Step-by-Step Instructions

Now for the fun part! Let's create your very own Midnight Harvest Pumpkin Cozy. This pattern is worked flat in pieces and then seamed together, which makes it easy to follow and perfect for beginners.

Finished Size

This koozie fits standard 12 oz (355 ml) cans or bottles, measuring approximately 4.5 inches tall with an 8-inch circumference.

Abbreviations

• CO: cast on
• K: knit
• P: purl
• K2tog: knit two together (right-leaning decrease)
• SSK: slip, slip, knit (left-leaning decrease)
• St(s): stitch(es)
• Rnd(s): round(s)
• Rep: repeat
• M1: make one (increase by knitting into the front and back of the next stitch)

Body of the Koozie (Worked Flat, Then Seamed)

Step 1: Cast On
With your orange yarn, CO 44 stitches. Leave a tail of about 6 inches for seaming later.

Step 2: Work the Main Body
Work in stockinette stitch (knit on the right side, purl on the wrong side) for 30 rows, ending with a wrong-side row. Your piece should measure approximately 4 inches tall. This forms the main body of your pumpkin.

Step 3: Shape the Top (Decrease Section)
Now we'll create the gathered top of the pumpkin by working decreases on the right side and purling on the wrong side. Follow these rows carefully:

• Row 31 (RS): K2, K2tog, K to last 4 sts, SSK, K2 (42 sts)
• Row 32 (WS): P all sts
• Row 33: K2, K2tog, K to last 4 sts, SSK, K2 (40 sts)
• Row 34: P all sts
• Row 35: K2, K2tog, K to last 4 sts, SSK, K2 (38 sts)
• Row 36: P all sts
• Row 37: K2, K2tog, K to last 4 sts, SSK, K2 (36 sts)
• Row 38: P all sts
• Row 39: K2, K2tog, K to last 4 sts, SSK, K2 (34 sts)
• Row 40: P all sts
• Row 41: K2, K2tog, K to last 4 sts, SSK, K2 (32 sts)
• Row 42: P all sts
• Row 43: K2, K2tog, K to last 4 sts, SSK, K2 (30 sts)
• Row 44: P all sts
• Row 45: K2, K2tog, K to last 4 sts, SSK, K2 (28 sts)
• Row 46: P all sts
• Row 47: K2, K2tog, K to last 4 sts, SSK, K2 (26 sts)
• Row 48: P all sts
• Row 49: K2, K2tog, K to last 4 sts, SSK, K2 (24 sts)
• Row 50: P all sts

Step 4: Bind Off
Bind off all stitches loosely. Don't pull your bind-off too tight—this will make seaming easier and keep the top of your pumpkin looking natural.

Helpful hint: The decreases create a gentle taper that mimics the natural shape of a pumpkin. The K2tog and SSK decreases are paired at each edge to keep the shaping symmetrical.

Stem

Step 1: Cast On
With your brown yarn, CO 6 stitches.

Step 2: Work the Stem
Work in stockinette stitch for 10 rows. That's it—simple and quick!

Step 3: Bind Off
Bind off all stitches. The stem will naturally curl slightly, which is exactly what we want for that charming, twisted look. Don't try to flatten it—embrace the curl!

Leaves (Make 2)

Step 1: Cast On
With your green yarn, CO 3 stitches.

Step 2: Increase Section
- Row 1 (RS): K1, M1 (increase by knitting into the front and back of the next stitch), K1 (4 sts)
- Row 2: P all sts
- Row 3: K1, M1, K to last st, M1, K1 (6 sts)
- Row 4: P all sts

Step 3: Continue Increasing
Repeat Rows 3-4 until you have 10 stitches on your needle. This creates the wide, rounded base of the leaf.

Step 4: Decrease Section
- Next Row (RS): K1, K2tog, K to last 3 sts, SSK, K1 (8 sts)
- Next Row: P all sts

Step 5: Continue Decreasing
Repeat the last two rows until only 2 stitches remain.

Step 6: Finish
K2tog, then fasten off. Weave in the ends. Your leaf should have a lovely pointed tip and a subtle central vein created by the decreases.

Make a second leaf following the same instructions.

Finishing and Assembly

Now comes the satisfying part—bringing all your pieces together!

Step 1: Seam the Body
Using your tapestry needle and the tail from your cast-on, seam the body using mattress stitch. This invisible seaming technique creates a beautiful, seamless tube. Leave the bottom open—this is where your can or bottle will slide in. The top will be naturally gathered by the decreases you worked.

Step 2: Attach the Stem
Sew the stem to the top center of the koozie. Position it so it curls naturally, giving your pumpkin that authentic, slightly whimsical look.

Step 3: Attach the Leaves
Sew the leaves at the base of the stem, one on each side. Position them so they fan out slightly, as if they're growing from the stem.

Step 4: Weave in All Ends
Take your time with this step. Thread each end through your tapestry needle and weave it through the wrong side of your work, going back and forth through several stitches to secure it. Trim any excess yarn.

Step 5: Enjoy!
Slip your new koozie over your favorite can or bottle, and enjoy your cozy Halloween beverage in style!

Tips for Perfect Results

• Check your gauge: A quick swatch will save you from disappointment. If your koozie comes out too small, try larger needles; if it's too loose, go down a size.
• Use cotton yarn: Cotton holds its shape beautifully and is more durable for repeated use. Acrylic can work, but it may stretch out more over time.
• Don't rush the seaming: A neat mattress stitch makes all the difference in how professional your finished koozie looks.
• Embrace imperfection: Handmade items have character. Your pumpkin cozy will be uniquely yours, and that's the beauty of crafting.

Make It Your Own

Once you've mastered this pattern, feel free to experiment! Try different color combinations—a white pumpkin with an orange stem, or a classic orange with a burgundy leaf. You could even add a few beads or buttons for extra charm. The possibilities are endless.

This Midnight Harvest Pumpkin Cozy makes a wonderful gift for friends, family, or coworkers. Pair it with a favorite fall beverage and a cozy mug for a thoughtful, handmade present that shows you care.

Happy knitting, and may your autumn be filled with warmth, creativity, and perfectly cozy beverages!
