Super Easy Crochet Hexagon Cardigan Pattern for Cozy Sweater Crafting

What if there was a way to make a cozy and stylish crochet cardigan that fits perfectly and is simple enough for beginners? You’re in luck! Today, I’ll walk you through creating an easy crochet sweater—a Hexagon Cardigan. Imagine a comfy sweater that’s nothing more than two granny-style hexagons sewn together. Sounds fun, right?

This easy crochet sweater pattern is perfect for those new to crocheting, but experienced crocheters will love it too. It’s a versatile, easy-to-wear piece that anyone can create! If you’re ready to add a lovely, homemade cardigan to your wardrobe, let’s grab some yarn and get started.

Check out my step-by-step video for this project:

Before we get started, gather your tools.

• Yarn: I’m using Chamois Chenille from Secret Yarnery. This yarn adds a plush, soft feel to your cardigan. You can adjust the yarn choice as long as it suits the gauge for your hook.
• Crochet Hook: A 7mm hook is perfect for this yarn thickness and stitch size. Any size 6 or bulky-weight yarn works great here.
• Stitch Markers: Optional, but they can be lifesavers, especially if you’re just getting started and need that extra guidance.

I love how this project begins so simply. For the crochet hexagon base, you’ll start with a magic ring. This clever little technique ensures a tight center for your hexagon and keeps your cardigan looking neat and tidy.

To make the magic ring, loop the yarn over your fingers, twist it into an X, and pull the working yarn through. The first few times might feel tricky, but a bit of practice goes a long way! Don’t worry if it’s tricky—luckily, I’ve created a magic ring tutorial on that.

After the magic ring, chain three. These first three chains will work as your first double crochet. Then, double crochet two more times into the magic ring, crossing over your tail. That brings you to three total double crochets, forming your first shell.

Once you’ve completed that, it’s time to start expanding for the hexagon.

The beauty of this pattern lies in its simplicity. Your first task is making six clusters (or shells) of three double crochets each, separated by chain two spaces.

Keep working into your magic circle, alternating clusters and chain spaces. Pull the yarn tail to close off the ring once you’ve made your six sets of double crochet clusters. These sets make up the sides of your hexagon.

To finish your first round, chain one and then crochet directly into the top of the chain three from earlier. This will create your first hexagon! Tighten the loop and weave in your tail for a nice finish.

At this point, I like to secure everything with a single crochet in the last stitch. You can mark this area with a stitch marker to keep track.

Just like that, we’re onto the second round! Work into those chain spaces from the first round. Chain 3, turn, double crochet two more times into the next space. Don’t forget your stitch marker if it helps guide you back to where the round ends.

You’ll continue this round by working three double crochets into each chain space. For each corner of your hexagon, you’ll need to crochet both three double crochets, chain two, and three more double crochets—all into the same space.

The pattern is magic once you start recognizing the flow of the corners. In each corner (where two sets of shells meet), make two clusters of double crochets with a chain two in between. Also, remember that side spaces only get a single shell—three double crochets with no chain needed.

Take note of how the corners stand out between the flatter sides. As you alternate between working the edges and corners, each round adds depth.

Every round, an additional cluster or shell will appear on each side. That’s the secret to making your hexagon grow into a larger shape, eventually becoming the “building block” of the sweater. By the time you’re done, it’ll feel like the easiest way to grow a project. The spaces between the double crochet clusters seed the growth naturally, and it’s pretty cool to see!

Now that you have your hexagon, let’s put it to work! You’ll fold your hexagon to create a “T” shape. One side will act as the sleeve, and the other will form half of the back and one side of the body of the sweater.

Visualize this: each hexagon forms half of the sweater when folded, creating a cardigan shape. Once you make a second hexagon—identical to the first—you can join them together to form the body.

Work your second hexagon just like the first one. Keep growing it until it’s roughly the same measurement as half your torso width (belly button to side ribs). For most people, 17 rounds should do it, but check your own body’s proportions to be sure.

Once you have two pieces, lay them down, aligning the edges. These will form the body and arms of your cardigan.

There are several ways to join the back. Some people prefer sewing or single crochet. But here’s a trick: I like to connect the two halves using slip stitches and chains to create a less visible seam. To do this, simply slip stitch into each space from both hexagon pieces simultaneously, chaining three as you move across. This way, you maintain the lacy flow of the pattern without creating any bulk.

Now you’ll see the structure of the sweater take shape. Joining the back creates the sleeve and body portion, which is a defining feature of this design.

The back seam becomes reinforced as you crochet it together, but remains flexible. You’ve essentially made a T-shirt shape with oversized sleeves, and you now have a real garment coming together!

At this point, I recommend using stitch markers liberally to make sure the sleeves and body stay lined up as you assemble. If you skip this step, it’s easy for things to get out of alignment, especially around the arm seams.

If symmetry is important to you, take a few minutes to check that everything matches up nicely.

The next step is adding the collar, which frames your sweater and adds a professional touch to the neckline. Your collar width will depend on your preference, often about two shells left open for the neckline.

Now it’s time to join the sleeves. Slip stitch from cuff to underarm along the open edges to close the sleeves. Ensure you evenly distribute your stitches during the joining process, so the sleeves don’t get twisted. Also, leave a few clusters free near the neck to allow room for your head!

Once the basic structure of the cardigan is complete, you can add a round of double crochet followed by single crochet around the entire edge. These finishing touches will give the cardigan a neat and clean look.

If you’re feeling extra creative, there are lots of ways to personalize your edges. For example, you could go a bit further by working extra rows of fancy stitches in contrasting colors.

Want a longer fit? Just keep adding rows to the bottom of the cardigan. You can alternate between double crochet clusters and careful filling of side seams. Just like drawing or knitting, each additional row builds gradually until it’s perfectly suited to your liking.

I promise the pattern grows on its own naturally—no need to overthink the process!

Speaking of personalization, you might want to add length to the sleeves too while you’re at it. The process is simple and the same as the rounds we worked before. For flaring sleeves, add a few extra shells in your chosen spots, and voila! You have a boho-chic-inspired sleeve.

Once the sleeves and body sections are complete, try on the sweater to check for fit. You can make final adjustments as needed, including narrowing any parts by adding smaller stitches around the seams. This ensures everything fits snug and flat.

FAQs

1. How many balls of yarn will I need?

The yardage depends on your size and the yarn brand. For an average adult size, you may need 5–7 skeins of chunky yarn (about 800–1000 meters total). Always buy an extra ball just in case.

2. Can I use a different yarn type or hook size?

Yes, you can use any yarn weight you like, but adjust your hook size to fit the yarn and check your measurements as you go. Thicker yarn will make a bulkier, warmer cardigan.

3. Is it possible to adjust the sleeve or cardigan length?

Absolutely. Before assembling, you can add extra rounds to your hexagons for a longer fit. For sleeves, just add as many rounds as you want for your preferred length.

4. What if my hexagons aren’t the same size?

Count your rounds carefully and lay both hexagons flat to compare as you go. If needed, add or undo rounds to make sure both are equal before assembly.

5. I’m struggling with the magic ring. Any tips?

Take it slow and watch the referenced video closely. If it’s too confusing, use the chain method as described in the guide. Both work, though the magic ring gives a tidier finish.

6. How do I wash my finished cardigan?

Always check your yarn label first. For most acrylic or chenille yarns, hand wash or use a gentle cycle, then lay flat to dry.

7. Can I make this cardigan for kids or plus sizes?

Yes, just measure as you go. Fold your hexagon in half and compare to half the chest width of the person who’ll wear it. Adjust rounds until the fit is right.

8. Do I need a stitch marker?

It’s highly recommended, especially for beginners. It helps keep track of corners and rounds to avoid mistakes.

9. How do I fix gaps or loose stitches?

Double-check your tension and make sure you’re using the right hook for your yarn. Practice will help you get more even stitches. In some cases, blocking your finished cardigan can help even out the fabric.
