CROCHET DIY | Granny Square Sweater

Let’s start off with a confession: I had never used the crochet technique before I started this project. I always thought that it would be waay too difficult and that the results would turn out to be a very poorly old fashioned (in a bad way) cushion cover.
But, wow was I wrong!

A few weeks ago I received the latest Mollie Makes Magazine which included a free crochet hook and I decided to give it a try. So I googled and youtubed to search for what would be the best beginner crochet DIY project. And I choose to begin with a simple granny square. One square let to two, than three and before I knew it I had a pile of squares and no idea what to do with it.

After deciding that I wanted to turn the squares into a sweater I made a plan and design on how I wanted it to look. I googled some more and I found a lot of helpful videos that I used as pieces of my sweater puzzle.
This resulted in many Netflix evenings on the couch with the cats and my crochet project, it felt wonderful. (I guess that this is also the point where I tell you that it is not a one-day project, not even a one-week project. I used a very small crochet hook and pretty thin yarn, and being a beginner I have to admit that one granny square took me about an hour..)

The sweater turned out just as I wanted it to and it has become my go-to indoor cozy cardigan!

Now on to the crochet DIY: since this is my first crochet DIY project, I simply want to show you my process. Crochet tutorials in writing are still very daunting to me and to be honest it feels like I am reading some sort of secret code. This means that I will show you the steps that I took, with the videos that I used to make the sweater.

I used three videos in total: (you can also find them below when you scroll down within the DIY steps, so you don’t have to leave this page to go to youtube)

Video 1 – This video is from SimplyDaisy* and she shows you how to make a Sunburst Granny Square.
Video 2 – This video is from WoolyWondersCrochet and it explains how to make a never ending square. (I used this video for the back and the sleeves of the sweater.
Video 3 – This video is from Bella Coco and she shows you how to attach the squares together with different techniques to choose from.

*”Simply Daisy” was the best video to start my first crochet project with. She explains everything very clearly and it is definitely suitable for beginners.




– 10 x 50g/199m of washable yarn ( I used 5 different colours, so 2 of each colour)

– A 3mm or 4mm crochet hook

– Scissors

CROCHET DIY | Granny Square Sweater


– Start making the granny squares* with the help of the video below:
– Make as many as you want. For this sweater pattern I made 32 squares:
> 20 squares for the front.
> 8 squares for the lower back.
> 4 squares for the cuffs.

*I mixed the colours to get a playful effect, but you can also stick to the same colour pattern for each square.


– To create a matched and detailed look, repeat step 4 from the video above to make an extra edge in the same colour yarn on each granny square. (this will also make the squares slightly bigger )
– repeat this step for all of the squares (see photo below)

– Make a giant granny square in a different pattern for the back of the sweater with the video below.
– The size of the square depends on the size of you sweater. I held the square to my back every so many rows to measure and see if I needed to go on or if I had reached the desired size.


– Make two slightly smaller granny squares with the video above for the top of the arms.
– Just as in step 3, I calculated the size by folding the square around the top of my arm to see if it was big enough.

– You will now have:

32 granny squares ( or as many as you like for your size and style sweater)
1 large granny square for the top of the back
2 medium sized granny squares for the top of the arms.

– To make sure that the sweater will fit, before you start connecting the pieces, you can use safety pins to temporarily pin everything together and try the sweater on. Simply add more rows to the bigger squares in case they are too small.

Now it’s time to play!

– Place the squares on a flat surface to arrange the back.
The biggest square goes on the top,
Place 8 small granny squares in two rows underneath it for the lower back,
The medium sized squares go at the top of the arms,
And each arm gets two small squares as cuffs.
– Rearrange the squares until you like what you see.

– Arrange the front
Place 20 small granny squares in rows of 4 underneath each other for the front. (the midline will be the opening of the sweater)
The medium sized squares go at the top of the arms,
And each arm gets two small squares as cuffs.
– Rearrange the squares until you like what you see.


– Attach the squares together with the help of the video above. ( I used the first method that she shows using the blue border colour)
– Attach everything together in the pattern that you chose for your sweater (see steps 6 & 7)

– To give the sweater a finished look, add a border all around*.
– I started with the left bottom corner of the sweater and used the 4th step from the first video to create a border.
– To go around the corners simply add a chain 3.
– I added 4 rows, but you can add as many as you like.

* You can see in the photo below what the border will look like at the neckline. The green and grey rows are my added border.

Optional Steps:

– Add a border to the end of the sleeves
– Add a zipper or buttons.
– Add lining and turn it into a coat.


And that is it! Those are all of the steps to make your own crochet DIY sweater!

    Great detailed video! As to the name of your unknown stitch using the mint green, it’s called a cluster stitch.

    • Lana Red Author 31st October 2016 at 9:21 am

      Hi Yvonne, thank you for your kind words! The video is actually not mine but made by the wonderful simplydaisy. I am a big fan and her video was the perfect way to learn crocheting for a beginner like me.

    I so love your jacket, I’ve never made anything for myself apart from throws ,cushions and toys for friends. It’s really spurred me on to have a go . X

      Thank you! And it’s lovely to hear that this project has spurred you to have a go! Happy crafting, and let me know how the project is going,I can’t wait to see what you made!x

  • Lina 21st July 2017 at 6:26 pm

    I love the jacket and plan to make one! I was wondering what yarn you used, the brand, cotton/acrylic, and the weight. Thank you!

    • Lana Red Author 21st July 2017 at 7:59 pm

      – 50 grams (199meters)
      – 80% acrylic/20% polyamide
      – Machine washable at 30°

        Thank you for the reply!
        I bought the yarn and want to make sure of my gauge! May you please measure one granny square so I can make sure of my size?
        Thank you again so much!

        • Lana Red Author 30th July 2017 at 12:01 pm

          Hi Lina, I measured a few squares and they are about 13cmx13cm each. This is an average, since some of them have been stretched a bit because I wear it a lot:)

  • Daisy E. 1st August 2017 at 3:18 am

    I just started crocheting this month and I LOVE what you have done! I will try it myself but probably make it shorter. THANK YOU SO MUCH for posting this! You INSPIRE me! Keep posting!

    • Lana Red Author 1st August 2017 at 8:37 am

      Hi Daisy, congrats on starting crocheting! And thank you for all of your kind words! Good luck with your version of the crochet sweater, and please let me know if you have any questions. Lana x

    Hi Lana,

    What a great idea!
    I crochstiched a big coverlet in 2016. It was so heavy (> 2 stones) is slipped of the bed. Okay, it was my first crocheting project. Now, I know what to do with all that wool.

    Thank you for sharing this lovely sweater on the internet.

    • Lana Red Author 5th August 2017 at 4:39 pm

      Hi! A big coverlet sounds like a great project! I might try it too in the winter season:)

      And greetings back from The Netherlands;)

  • Aparna 2nd November 2017 at 1:49 pm

    Can the back of this sweater be just one big granny square instead of having some granny square in the down back?

    • Lana Red Author 20th November 2017 at 6:40 pm

      Hi! When you crochet the square and want it to reach the length of the front, it means that the sides will also get wider. So I wouldn’t recommend it. Because not only will the sides get wider, the neckline will also not fit with the front anymore.

  • Aparna 2nd November 2017 at 1:50 pm

    I plan to make this sweater for a toddler

    • Lana Red Author 20th November 2017 at 6:37 pm

      That is such a wonderful idea! I can imagine that it will look extremely cute on a toddler:)

  • Claire 28th November 2017 at 2:37 am

    I love this, cant wait to make one! Did you use the same size hook for both the small and large squares?

    • Lana Red Author 29th November 2017 at 8:41 am

      Hi Claire! Yes I used the same hook for all of the squares:) Happy crocheting!! Lana x

  • Michelle 14th December 2017 at 3:45 am


    Thanks so much for sharing this pattern. I’ve been looking for one like this for quite a while, & now I’ve found it. It’s really cool, & I look forward to making it & then wearing it. If it works out for me, I’ll make some for other people as well.

    Just so that I have an idea of where to start, if you don’t mind me asking you, what size sweater do you wear? I’m only asking to give me an idea of how many squares I’ll need, which’ll probably be more than what you made.

    Thanks again. :)

    • Lana Red Author 14th December 2017 at 8:43 am

      Hi Michelle! I usually wear a size EU38 (medium) which I think is a US size 8.
      I made the sweater slightly oversized, but paid special attention to the sleeve length and the position of the shoulder seam. These really make the sweater look ‘fitted’.
      Have fun crocheting! And please let me know how it turns out!! Lana x

  • Michelle Knowles 14th December 2017 at 4:43 pm

    Thanks, Lana. That helps a lot. 😊

    It’ll be a while before I make it, but I will let you know. ☺

  • Audrea Wulf 29th January 2018 at 9:46 pm

    I am having trouble making the big back square fit with the 4 small squares for the back…should I make the big back square bigger til it fits my 4 small squares….sorry I’m new to this …but enjoying the project as it’s coming along..

    • Lana Red Author 29th January 2018 at 10:12 pm

      Hi Audrea! It’s great to read that you are making your own sweater!
      And yes, you can continue adding rows all around the big square to make it fit with the 4 small ones. If you are new to this (which I also was when making the sweater) it is possible that the tension between the stitches isn’t always the same. So it is perfectly ok for your squares to turn out a bit different than the example videos. Just as long as the final sweater fits you well, it will all be fine:)

  • Kathy 31st March 2018 at 2:21 pm

    I’m totally impressed that this is your first crochet project!

    • Lana Red Author 1st April 2018 at 8:14 am

      Thank you so much!!
