EASY Granny Square Cardigan

The granny square is a classic and basic crochet pattern - it is often one of the first items a person learns to make when first crochet. 

I love Granny Squares - there are so many variations how to use this pattern when crocheting decorative and useful items, blankets, bags and placemats, home decorations and also: wardrobe.


My tutorial covers how to make a true granny square - worked in the round, using double crochet stitches in clusters of three with a chain stitch separating the clusters.

It is super easy using Granny Square pattern to create a wonderful cardigan - it is Spring - so I chose Spring green colour and I am so happy how it turned out!

Let's start or PIN this idea to your Pinterest boards for later.




So let me now get started and tell you what you will need in order to crochet this amazing Spring Green Cardigan.

Spring Green Cardigan Directions

For this girls size you will need:
Red Heart Super Saver: 7oz/198g, 364yrs/333m, Spring Green, size 4 medium, 100% acrylic, 2 skeins


For this pattern you will need 5.5, 4.0 and 3.5 mm crochet hooks.

This Cardigan is made as one panel, one square (crocheted as a one part) – it is crocheted together.

Size: girls size - this can easily be adapted to a smaller size or bigger size just by reducing or increasing the number of rows and to make a square smaller or bigger.

Difficulty Level: Level 1 – Easy, for beginners

US crochet term:

SlSt – slip stitch
CH/s – chain/s
SC – single crochet
HDC - half double crochet
DC - double crochet
FPDC - front post double crochet
BPDC - back post double crochet
SK - skip
T - turn
ST/s - stitch(es)
REP - repeat
YO – yarn over

Special stitches used: hdc in the 3rd loop only - the 3rd loop is hidden under the back loop.

Special stitches used: front post double crochet (fpdc) and back post double crochet (bpdc)
Front and back post crochet stitches are used to create wonderful texture in crochet. Instead of making your stitch through the loops at the top of the stitch, you make it around the stitch. Everything else stays the same. The most challenging things about crochet post stitches are knowing where and how to insert the hook. There are front post stitches and back post stitches.
For front post double crochet stitches (fpdc): yarn over, insert your hook from front to back then from back to front around post of stitch indicated, yarn over, pull through stitch, then finish your double crochet as normal, yarn over, pull through 2 lps, yarn over, pull through last 2 lps
For back post double crochet stitches (bpdc): yarn over, you insert your hook from back to front then from front to back around post stitch indicated, yarn over, pull through stitch, then finish your double crochet as normal, yarn over, pull through 2 lps, yarn over, pull through last 2 lps


Pattern Notes
1) The direction shown are for girls size but can be easily converted into bigger size or smaller size – just measure your Granny Square bigger or smaller.
In Cardigan part: a ch3 at the beg of row counts as dc
In Collar part: A Ch 2 at beg of the row counts as hdc throughout.



Pick up the 5.5 mm crochet hook and start the Granny Square - make a magic ring and chain 3. 

R1: Make the first Double Crochet Cluster: groups of dc stitches are the building blocks of crochet granny squares. Each cluster consists of three side-by-side double crochet stitches. The "chain 3" counts as the first double crochet stitch in the first cluster. 
To complete the cluster, crochet two more dc into the magic ring. You should now have what looks like three dc stitches next to each other in your first group.

Then chain 1 and start to crochet the second dc cluster.
Make another cluster of three double crochet stitches. Crochet 3 dc stitches into the magic ring and chain 1. 

Repeat the previous instructions two more times. You will have four clusters of double crochet with a chain one space between each of them, and the last chain one hanging on the end. To close the round and create the square shape, slip stitch into the top of the first ch 3 from the beginning.
This ends the first round - we just finished Round One (R1) of the Granny Square

R1: Work in Magic ring: ch3 (1dc), 2 dc, ch1, 3 dc, ch1, 3dc, ch1, 3dc, ch1, sl st to top of ch 3 to close round.


R2: Round Two of the Granny Square
To start round two and all other rounds, chain 3 - same as in the first round, this counts as the first double crochet of the first set. Complete the First Double Crochet Set: work 2 double crochet stitches right next to the chain 3 in the open corner immediately below the chain 3. With the first dc cluster finished chain one.

Work around R2 of the Granny Square:
In the corner, crochet three double crochet stitches, chain 1, and crochet another 3 double crochet stitches, all in the same ch1 in the corner. Chain 1 and work every corner of the granny square this way, except for the starting corner.
Crochet around the granny square, repeating the previous instructions in each corner.
When you reach the corner where you started, make another cluster of 3 dc stitches, then chain 1.
Slip stitch to the top of the first chain 3 to close the round. The final corner should now look like all the others.

R2: Ch 3 (1dc), 2 dc in same corner sp, ch 1, repeat 3 times: working in next corner sp: (3 dc, ch 1, 3 dc, ch 1), ​3 dc in starting corner, ch1, sl st to top of first ch 3 to close round.


R3: Round Three of the Granny Square
Begin the third round the same as the previous round.
Chain 3, then make 2 dc stitches in the same ch1 space. Chain 1.

Work Double Crochet Clusters on the Side = in this round, crochet a cluster of 3 dc stitches in the space on the side of the square, then chain 1.
Crochet Around the Third Round: Work into the corner the same way as the previous corners. Make a cluster of 3 dc stitches, chain 1, make another cluster, and chain 1.
As you work your way around the granny square, repeat the previous instructions so you get a cluster on each side and two clusters in each corner.
When you reach the last corner, which was also the starting corner, make a cluster of dc stitches, chain 1, then slip stitch to top of firs ch 3 to close the round.

R3: ch 3 (1dc), 2 dc in same corner ch1 sp, 3dc in next ch-1 sp, ch 1, Repeat 3 times: working in next corner sp: (3dc, ch1, 3dc, ch1), 3dc in next ch1 sp, ch1, till you reach starting corner: 3dc, ch1, sl st to top of first ch 3 to close round.​


Growing It Larger
Now it is easy to grow the granny square larger. With each round, you will have more spaces and groups of dc along each edge. Keep adding them to grow the granny as big as you want.

I made 28 rounds of Granny Square pattern.
Measurement: 30 inch x 30 inch  //  75 cm x 75 cm


Time to join your Cardigan:

Directions: Fold your work in half with wrong side facing out. Fold the Cardingan over the any side - it is a square, marrying the corners. 
Take a smaller hook - I used 3.5 mm crochet hook.

You will now begin to join the Cardigan by slip stitching 2 sides.
The other sides are to be left open.
Start slip stitching from the corner, join st to st by sl st, make sure the rows are aligned, join first 9 clusters of 3dc together, leave 5 cluster of 3dc open for the arm hole.

Then continue crocheting the sleeve around the arm hole.


Take a smaller hook - I used 4.0 mm crochet hook.
Work on right side.
Let's continue with Granny Square pattern: ch3, 1dc in seam, ch1, repeat this group in each ch1 sp till end of round: (3dc + ch1), then 1dc in seam and sl st to top of first ch 3 to close round.​
Repeat instruction above and work group (3dc+ch1) in each ch1 sp and make 12 rounds for sleeve.


You may like your sleeves to be longer if so just add more rounds until you are happy with the length.


Take a smaller hook - I used 3.5 mm crochet hook and finish sleeve with a border.
R1: ch3 (1dc), 1dc in each dc from previous round, skip ch1 (don't work in ch1 sp), 
sl st to top of first ch 3 to close round.​
R2: ch2 (don't count ch2 as a stitch), repeat till end of round: 1 fpdc around next 2 dc from R1, 1 bpdc around next 2 dc from R1, at the end of round sl st to top of first ch 3 to close round.​
R3: ch2 (don't count ch2 as a stitch), repeat till end of round: 1 fpdc around next 2 fpdc, 1 bpdc around next 2 bpdc, at the end of round sl st to top of first ch 3 to close round.​


Fasten off and repeat the same for the second sleeve on the opposite side.
Fasten off. Weave in all ends.

With the Cardigan still folded, grab the middle of the long side and open it.
You will now add a border to your neckline opening.


Use crochet hook 5.5 mm
Begin working from the joining.
Rejoin the yarn.
R1: ch2, 1 hdc into each st across (place a hdc into the seam on the opposite side as well), join the row by sl st in the 2rd ch from beg to close round

R2: ch2, 1 hdc into each hdc across in 3rd loop only, join the row by sl st in the 2rd ch from beg to close round
R3 = repeat round 2
Fasten off your work and hide all loose tails and and you are all done with your Spring Green Cardigan.


The collar width: 5cm
The sleeve width: 12cm
The sleeve long: 19 cm 

The length: 80 cm
