Not only is it easy to make but the pattern adapts easily to fit any size, child or adult.

You can use any yarn weight or fibre to crochet this hexagon cardigan as it is made to measure.

Cropped cardigan?  Or longer cardigan?  My pattern is so versatile that you can make your cardigan in any length you want!

If you can crochet a granny square you will be able to crochet the hexagons.

I’ve used basic crochet stitches – double crochet (US single crochet), treble crochet (US double crochet) and chains – making this project suitable for beginners.

Design Inspiration

It’s difficult to find a cardigan that fits me well.  I’m not very tall so the sleeves are ALWAYS too long. A petite fit is a bit hit and miss too.

I love the hexagon granny cardigans but wanted this cardigan to be a bit different.  I knew it would be easy to crochet a hexagon cardigan made-to-measure.

How the pattern is worked

You can use any weight yarn and fibre for this pattern.

You will need to go up a hook size from the recommendation of your yarn for the body of the cardigan and down a hook size for the edging and cuffs.

I used Aran/Worsted weight yarn with a 6mm hook for the body and 4mm hook for the edging and cuffs.

Two hexagons are crocheted first.  They are crocheted in rounds. The pattern is 3 rounds of treble crochet (US double crochet) and one round of treble, chain 1, skip one.

Once the hexagon is folded, the sleeve seam is made by working slip stitches.

*If you know you want to add length to the sleeves and a cuff – you can do so after joining the top seam of the sleeve.  If like me, you weren’t sure, you can leave extending the sleeves to the end.*

Next, rows are added to the back of the cardigan from the top to the bottom.  The extra rows are needed as space for the neck.

The two sides are sewn together either using slip stitch or double crochet (US single crochet).

If you wanted a cropped cardigan, you would then go on to edging the front/neck to finish your cardigan.

For a longer cardigan, the yarn is re-joined to the bottom of the cardigan to work the extra rows to extend the length.

The edging along the front and back of neck is worked in rows with double crochet (US single crochet) and a hook size smaller than recommended for the yarn you are using.

I realised once I’d done the edging and tried on my cardigan again, I wanted my cardigan to be longer!  Instead of unpicking/frogging what I had done, I decided to repeat the edging above at the bottom of the cardigan.  And that’s the beauty of crochet (or anything handmade) isn’t it – the imperfections are what make it unique 🙂

Finally, you will need to decide whether you want to extend the sleeves and/or add cuffs.

If you want to extend your sleeves, you’ll continue with the pattern used in the hexagon rounds. If you also want to add cuffs, you’ll need to leave space between the end of the sleeve and your wrist.

There are three rounds of decreasing before the cuffs are crocheted.

Double crochet in the back loops is used for the cuffs.

Basically, once the hexagons are crocheted, the pattern extends the width, the length, the sleeves and adds edging/cuffs.

Yarn

I used Hobbii Carnival in Copenhagen 05 (Aran/Worsted) which is 100% premium acrylic yarn.

It has a clear but gradual colour shift that I thought would work well for this project. I tried to match up the colour changes and I was successful in some places but not others!

It’s machine washable at 30 degrees making this ideal for wearables.

If this yarn isn’t available, a list of substitutes is available on YarnSub.

You could use any Aran/Worsted weight yarn with this pattern.

Pattern Notes

  • Chain 1 does not count as a stitch
  • Chain 3 does count as a stitch
  • Hexagons start with chain 4 and slip stitch to first chain to make a circle but if you prefer to start with a magic circle, then that’s fine
  • Hexagon rounds end with a slip stitch at the top of chain 3 and begin with slip stitches to the next corner space
  • Hexagons should be ruffled and not ‘flat’

  • The size of your hexagon is determined from the measurement of the width of your upper arm.  You will need to measure round your arm (giving an extra 5 – 10cm for movement/positive ease).  I measured a sleeve from one of my favourite sweaters.  I crocheted a total of 14 rounds for my hexagons (I’m a UK 16)

  • Do not fasten off when you finish the hexagon as you will continue with seaming the sleeves
  • Once sleeves are seamed, try on and determine the extra rows needed at the back (space for your neck)
  • The balloon shape for the sleeves is made by decreasing for 3 rounds before crocheting the cuffs
  • The cuffs are made by continuing after decreases on the sleeve. Chain enough stitches from the end of the sleeve to your wrist. You will work back down the chain and slip stitch to the next stitch to work back up the cuff in back loops only and continue around to join the cuff with a slip stitch.
