You can use any combination of colours or granny square designs, making this cardigan unique to you (I think the flower square I used in my granny square tote bag would look fab!).

Keeping your crafting costs down?  Using your odds and ends from your stash will work well for this project.

My free granny square crochet cardigan pattern is suitable for beginners.

I’ve added rows of granny stitch/treble clusters to the length on the front and the back.

The edging for the front of the granny square cardigan is made by crocheting rows of slip stitches.

Design Inspiration

My mother-in-law (Stella) was coming to stay for a break and when we go out for retail therapy, she always buys a top or a cardigan.

I had her favourite colours in my stash, wanted a project I could pick up in short bursts of time and something that was quick and easy to make.  Designing this crochet granny square cardigan pattern fitted the bill exactly 🙂

How the pattern is worked

I’ve written the pattern in UK and US Crochet terms.

The large classic granny square for the back is worked first.  The size is worked out using your chest circumference measurement.

How to determine the size of your granny square is in the Measurements section.

Smaller classic granny squares are crocheted next. 

For the sample size of M/L I crocheted 16 squares of 4 rounds each for the front of the cardigan. 

These granny squares are sewn together to form two columns.  For the sample size of M/L, I needed 4 granny squares in each column lengthwise to match the back.

Length is added by crocheting granny cluster stitches to the bottom making sure the front and the back match.

Rows of granny stitch need adding to match the back of the cardigan

The sleeves are crocheted separately and begin with a ribbed cuff.  To match the granny squares, the sleeves are worked in rounds of granny cluster stitches.  The sleeve is sewn into the armhole.

To assemble, the shoulders are seamed, making sure there is an opening of 20cm (10 cm either side of the middle of the back) for the neck opening.  The sleeves are sewn in next followed by continuing to sew the side seam.

Finishing off: the front edging of each side is crocheted in rows of double crochet (US single crochet).

Yarn

A few months ago, I tested out buying yarn in one of Joann’s sales and Big Twist Aran/Worsted yarn was a complete surprise in the package.  Some of the yarn I ordered wasn’t in the package but Big Twist was. 

At the time I didn’t have a project in mind but it was a good match for this project.  I’m glad I was able to try it out.

This yarn is durable and functional.

I needed extra and was able to colour match with Emu Classic Aran I had in my stash.

The Emu Classic does work out cheaper than the Big Twist so if you’re in the UK and thinking of buying your colours, this range is worth considering.

Pattern Notes

  • Chain 1 does not count as a stitch.
  • Chain 2 counts as a treble crochet (US double crochet).
  • Chain 4 counts as a treble and 1 chain.
  • Granny squares start with a ch4 to begin and working into the first chain.
  • Large granny square (back) and smaller granny squares (front) have chain 1 space between clusters.
  • No chain spaces are used between clusters on the sleeves.
  • Weave a length of yarn through the last stitch when crocheting the sleeves to guide you for where to work the last stitch of each round (the closing stitch isn’t worked into).
  • Use a standing stitch to join new yarn colour:  make a slip knot on hook, insert into chain space, yarn over, double crochet.
  • Weaving in ends for each square before crocheting the next one is less overwhelming!
  • When sewing in the sleeves, match the clusters.
  • Read through the pattern before you start.
  • Sample size is M/L

Measurements

This granny square cardigan is made-to-measure.

Large granny square (back): Measure your chest circumference with a tape measure and divide by 2 (for the front and back).  Add between 5 – 10cm for movement (known as positive ease).

Smaller granny squares (front): 2 columns of granny squares for each side (left and right) are needed so you need to divide your chest measurement by 4 (don’t forget to add positive ease!).

Sleeves:  Measure the length of your sleeves by either using a favourite sweater or cardigan and using the same length or try on the sleeve as you crochet for the perfect fit.

How to assemble granny square cardigan

Front

Join the columns of granny squares for the left and right front either:

  1. Sl st squares together – for a patchwork effect, sew with WS facing inwards (the seam will show on the RS of the cardigan) or with RS facing inwards (no seams will show)
  2. Sewing squares together using whip stitch – work with the RS facing inwards

I assembled the granny squares by sewing two together and then each group of two going down the column.

16 classic granny squares with lilac, blue and purple skeins of yarn
Yellow = first join for all granny squares Green = second join

Once joined together, place the granny square panels on top of the back and check the gap between the front and left isn’t too wide.

If it is too wide, rejoin yarn and work rows of granny stitch clusters.  Keep in mind there is also a double crochet border.  Make sure you work the rows on the edge that will be the centre (and not the side seam).

Shoulder seams

With RS facing inwards, find the centre of the back and place a stitch marker 10cm to the left and another stitch marker 10cm to the right for the neck opening.

Seam the front panels from the edge of the front towards the stitch marker in the middle for both right and left.

Sleeves and Side Seam

Pin the sleeves in place and matching the clusters, sew around the armhole beginning from underneath the armhole. 

When you reach where you started, DO NOT FASTEN OFF.  Continue sewing the side seam matching the clusters.

Fasten off and weave in ends.

Edging

Front and back of neck

Row 1:  Rejoin colour of your choice to the neck opening on the RHS, ch1, dc evenly along the front right, along the back of the neck and the left front, turn

Row 2: ch1, sl st in the same st and ea st along.  Fasten off and sew in ends.

Front Opening

Rejoin yarn at the bottom of the left opening, ch1, sl st in this st and ea st across.  Fasten off and weave in ends.

Rep above for the right opening.
