Welcome to the Seaside Chunky Knitted Cardigan pattern. I knitted this whilst on a trip to the Jurassic Coast and it will always remind me of Durdle Door and Weymouth where I spent a lot of time as a child. It is designed to be worn open and slightly oversized and the size is easily adjustable if you’re tall, short or just fancy something a little off-piste.

This cardigan is super cosy, chunky and perfect for beginner knitters.

Difficulty - Advanced beginner (Can you knit a hat? If so, you can make this cardigan!)

Techniques used

1) Knit
2) Purl
3) Knit two together decrease (K2TOG)
4) Pick up stitches
5) Cast on
6) Cast off
7) Mattress stitch and perpendicular and horizontal seaming
8) 1 x 1 rib (knit one, purl one)

Needles required - 10 mm and 12 mm straight knitting needles

Suggested yarn -

John Lewis 100 % wool chunky yarn (shop here) knitted together with Rowan Alpaca Classic DK yarn (shop here).
Note: This yarn was a payday treat and fairly expensive but it is lovely, soft and squishy. I’ve listed some suitable alternatives below but please do check tension if using a different yarn!

This pattern currently has not been tested for the 2XL and 3XL sizes. I made mine in a size medium and scaled it up and down with some simple maths therefore yardage is approximate. If you have any comments or feedback of this pattern I would love to hear from you!

Please note: I have tried to cover a range of sizes however if you feel none of these are right for you, please do contact me and I'd be happy to work out stitch counts and yardage so you can enjoy this pattern!

The cardigan is knitted up flat on straight needles in five parts and sewn together using mattress stitch. Stitches are then picked up along the fronts and neckline and knitted in 1 x 1 rib. As it is knitted flat, the size is very easily adjustable.

Stitching together

The cardigan is sewn together using mattress stitch, the perpendicular and horizontal seaming technique. Check out my post (here) about the best tutorials I’ve found for help!

1) Starting from the edges, sew the back and the two front pieces together using the horizontal seaming technique.
2) Lining up the stitches carefully, sew the top of the arm to the back and body pieces using the perpendicular seaming technique. Repeat for both arms.
3) Starting at the 1 x 1 rib at the wrist sew up the arm and down the body using mattress stitch.
4) Repeat for both arms.

Front ribbing

1) Starting at the bottom of the right front panel (the right as if you were wearing the cardigan), pick up every other stitch with your 12 mm needle. Make sure you pick up the last stitch of the left front panel even if it’s not ‘the other stitch’.
2) Knit 3 rows in 1 x 1 rib.
3) Cast off.

Weave in all ends and block if necessary.

I added three buttons just for effect however as the knit is chunky, buttons should fit in between the stitches so button holes are not required.

All done!
