Crochet - How to Make a Boxy Cardigan


Hello. It’s been very chilly here the past few days, I’m not complaining this winter has been a particularly mild and wet one. I’ve been patting myself on the back for completing my boxy cardigan over the holidays as I’ve reached for it nearly every evening since I finished it. It’s such an easy garment to wear, it’s simple boxy design means I can pop it over almost every piece of clothing for an instant hit of comfort. I’ve been asked lots of questions on it over the past months so I thought it deserved its own blog post…

This will be more of a how-to than a full pattern as it’s certainly not a new design idea, all I’ve really done is assemble some squares into something wearable! But here goes…

How To Crochet A Simple Boxy Cardigan

Project Notes

This cardigan is made up of squares using the join-as-you-go method – I worked a total of 52 squares for my cardigan and they each measure approx. 12cm x 12cm (4.7" x 4.7") once joined. The squares were joined into a large rectangle shape with a gap of 4 squares to create a neck opening. I’ve drawn a diagram below which I think shows the construction better than I could explain in words. You can choose to make all 52 squares first (up until the final round) and then join or join each square as you go.


Drops Puna, 50g/110m/120yds, 100% Alpaca, shade: 04 Taupe – I used a total of 700g of yarn for my cardigan so I would suggest between 14 and 15 balls if you are using the above yarn. I bought mine from Wool Warehouse over the course of the year (and only when they had offers on!) For yarn substitutions try a DK weight yarn for a similar effect.


4mm / G-6

Other Tools

Tapestry needle, tape measure and scissors

My finished cardigan measured approx. 84cm (33") in width and 55cm (21.5") in length (including the border). I did not need to block it but as I wore it the weight of the cardigan meant that length dropped to approx. 60cm (23.5") so it may be worth keeping that in mind if you are using the same yarn. Each joined square measured approx. 12cm x 12cm (4.7" x 4.7"). I would suggest working and joining a couple of squares first to get your measurements, you can then add extra squares/rows if you need too.


I used the sunburst granny square pattern for my squares. It’s a free pattern, I’ve linked to what I think is the original design by Priscilla Hewitt here

I’ve not used the full square, I simply followed rounds 1 - 4 of the pattern and used round 5 as my joining round. Alternatively, there is a good video tutorial here

You can use any type of square you like for this project, there’s a link to my simple reversible granny square pattern here if you’d prefer to use that. I joined my squares in the fifth round using the join as you go method; 3tr (US 3dc) in each space, slip stitching into the space of the square to be joined and 3tr, ch2, 3tr (US 3dc, ch2, 3dc) into each corner. There’s a good video tutorial here for using the join as you go method.

I joined mine in rows of 7 to start with, so I worked 4 rows of 7 squares – which made up the back of the cardigan. I then worked 4 rows of 3 squares onto this panel, left 1 square space, then joined another 4 rows of 3 squares – these two panels make the front of the cardigan. Again have a look at the diagram below.

Once all the squares are joined (as image above) simply sew up the side seams, using the same yarn and a tapestry needle, with a whip stitch or whichever method you prefer. I left approx. 40cm (15.8") gap for armholes. I then worked a round of dc (US sc) around the armholes and the bottom and neck opening. Then a further round of dc (US sc), and three rows of front post tr (US FPdc), back post tr (US FPdc) ribbing around the bottom only – again I've linked a video tutorial here

Most importantly, feel free to experiment with squares, shape, edgings, add buttons or simply fasten with a shawl clasp as I have. It really is the most simple pattern and was just a joy to pick up and put down over the months.

So I think that's everything, you can also see the finished project up close in episode 27 of my crochet vlogcast over on YouTube. I hope I've covered everything but if you do have any questions feel free to drop me an email at: This email address is being protected from spambots.

Bye for now,  Em xx
