Key Features and Construction Steps:
- Materials: Lightweight #3 yarn (Mandala Baby is used in the tutorial) with a 6mm crochet hook for a loose, drapey finish.
- Hexagon Construction: Made using a variation of the classic granny square, forming six corners for a hexagon instead of the traditional four.
- Joining Hexagons: Each hexagon is folded to form an “L” shape, creating half of the cardigan. The two halves are then sewn or crocheted together.
- Custom Sizing: Cardigan size is adjusted by comparing measurements to a favorite sweater and tailoring features like sleeve width and body length to your liking.
- Back Panel and Edge Finishing: A back panel is added to widen the cardigan, while borders and cuffs give a polished, finished look.
The construction starts by crocheting two hexagons using the easy-to-master granny stitch (clusters of 3 double crochets separated by chain spaces). Instead of forming a typical granny square, you’ll work additional clusters to create a six-sided hexagon. This simple adjustment transforms a familiar pattern into something stunningly unique. A key tip is to turn your work at the end of each round to keep the piece from skewing—a small habit that goes a long way toward keeping the hexagon evenly shaped.
Once the two hexagons are complete, they’re folded into “L” shapes to serve as the foundation for the cardigan. Each folded hexagon constitutes one sleeve and one half of the body. The arms and back seams are then stitched or crocheted together, forming the basic cardigan structure. Customization is the star of this design: use a favorite sweater for measurements to determine ideal sleeve width and overall fit. For example, you can make the sleeves wider or tighter, depending on your style preference.
After assembling the main structure, gaps at the back of the cardigan are filled in with a back panel. Using the granny stitch again, this simple addition bridges any width deficiencies without impacting the fitted look of other sections. Adding this panel ensures the cardigan accommodates various body shapes while maintaining a handmade, tailored finish.
The next step is to fine-tune the sleeves and length. Sleeves are extended by continuing the granny stitch in the round, with the option to add playful color changes or stripes. Similarly, the body length can be extended to suit your preference—cropping it for a light layer or working more rounds for a cozy, snuggly fit. Clean edges are formed by adding borders with simple half-double crochet or double crochet rows, bringing everything together.
Finally, the neckline and front edges are bordered to give a cohesive, polished look. The border ties the entire garment together, allowing for neat finishing and a flattering drape over the shoulders. You can match or contrast the edging colors for added flair!

Step-by-Step Pattern
Materials
Here’s what you’ll need to recreate this beautiful cardigan:
- Yarn: Mandala Baby Yarn (Lightweight #3). The colorway featured in the tutorial is Echo Caves. You’ll need approximately 3 skeins (590 yards per skein).
- Crochet Hook: 6mm (J-10) hook. A larger hook helps create a lightweight, airy feel. The yarn label recommends a 5mm hook, but using 6mm ensures good drape for your cardigan.
- Optional Tools:
- Stitch markers
- Scissors
- Yarn needle (for weaving in ends)
- Measuring tape (to customize the cardigan’s size)
Pattern Instructions
Step 1: Create the Granny Hexagon
- Foundation Ring: Start with a slip knot and chain 4. Slip stitch into the first chain to create a loop.
- Round 1:
- Chain 3 (counts as the first dc) and work 2 dc into the ring.
- Chain 1.
- Work 3 dc + ch 1 five more times into the ring (for a total of six clusters with chain spaces between).
- Slip stitch to the top of the chain-3 to join.
- Round 2:
- Turn your work.
- Chain 3 (counts as the first dc). Work 2 dc into the first chain space.
- In the next chain space, create a corner by working 3 dc, ch 2, 3 dc into the same space.
- Continue working 3 dc into each chain space and 3 dc, ch 2, 3 dc into each corner space. Slip stitch into the top of the chain-3 to join the round.
- Round 3 and Beyond:
- Turn your work after every round.
- In each chain-2 corner space, continue making corners (3 dc, ch 2, 3 dc).
- For spaces along the edges, simply work 3 dc.
- Repeat until the hexagon reaches the desired size for your cardigan sleeve and body.
Tip: Use a sweater you like as a size guide. Fold the hexagon into an “L” shape, and ensure the sleeve width matches your measured sleeve length.
Step 2: Create the Second Hexagon
Repeat Step 1 to create a matching hexagon.
Step 3: Assemble the Cardigan
- Folding the Hexagons: Fold each hexagon into an “L” shape. Align the two Ls together to form the body of the cardigan.
- Join the Back: Seam the back using either a whipstitch with a needle or single crochet. If you’re using a yarn needle, work the stitches so the seam lies flat.
- Side Panels: To ensure you achieve your desired body width, use the granny stitch to create side panels that fill in the back or extend the front. Connect them using slip stitches or single crochet.
Step 4: Add the Sleeves
- Seaming the Sleeves: Seam the sleeves using a mattress stitch or work through the inner loops of the granny clusters for a clean finish. Be cautious around the armhole to maintain symmetry.
- Extend the Sleeves: If the sleeves are too short, attach yarn to the wrist opening and work additional granny stitch rows until the sleeves reach your preferred length. Alternate colors if desired to match or contrast the cardigan.
Step 5: Add the Body Length
- Attach your yarn at the bottom edge of the cardigan and work granny clusters across the width.
- Add as many rows as you need to achieve your desired length.
Step 6: Add a Border
- Work half double crochet (hdc) stitches evenly around the entire cardigan opening (collar, hemline, and front edges).
- Repeat this border 2-4 times to build width and clean up any uneven edges. Optional: Add a final round of single crochet stitches for a polished finish.
Pattern Question
Question: How can I adjust the cardigan for a more fitted look?
Answer: Use a favorite sweater as a reference to measure sleeve and body widths. Customize your hexagons and panels by stopping when your dimensions match for a tailored fit.
Troubleshooting and Suggestions
- Common Issue: Uneven Corners
If your hexagon corners look uneven, make sure to chain two between the double crochet clusters in each corner. Turning your work after every round will also prevent warping. - Keeping Edges Clean
Use stitch markers to identify the tops of your chain 3 turning stitches, ensuring a neat and consistent look when joining rounds or panels. - Adjusting Fit
For a wider body or longer sleeves, simply continue working additional rounds of the granny stitch around the hexagons. Make sure to measure as you go for a custom fit. - Creative Modifications
Experiment with color! Try bold, striped patterns, soft ombrés, or even contrasting borders. You could also leave the cardigan open for a casual look or add buttons or ties for more structure. - Adaptations
The granny hexagon method can easily be used to create cropped boleros, vests, or even lightweight beach cover-ups. This is a versatile base, and your creativity is the only limit!
