Free Granny Square Shrug Crochet Pattern: The Aveline Cocoon Cardigan

Made from just six oversized granny squares, my Aveline Cocoon Cardigan is an easy crochet shrug with clever construction and beautiful drape.

My Aveline cardigan combines the timeless appeal of granny squares with an easy-to-make cocoon silhouette. Made from just six oversized granny squares, it’s a relaxing project with minimal seaming that creates a lightweight layer with a soft, fluid drape.

The simple construction makes it an enjoyable project for confident beginners who want to try making their first cardigan without tackling complicated shaping, while experienced crocheters will enjoy the relaxing rhythm of making the oversized granny squares.

Whether you’re looking for a shrug to throw over a dress or an extra layer for cooler evenings, Aveline is comfortable to wear and easy to style with your everyday wardrobe.

Skill Level

Easy

My Aveline Cocoon Cardigan is suitable for confident beginners and intermediate crocheters. If you’re comfortable working double crochet stitches, chain spaces and joining granny squares, you’ll find this an enjoyable garment project.

The construction is straightforward. You’ll crochet six oversized granny squares, join them to form a rectangle, fold the fabric in half and sew two simple side seams before adding the edging.

Sizing

The table below shows the finished size of each cardigan, the granny square size needed, the number of squares required and the approximate yarn quantity.

Choose the size that best matches your preferred fit and check the finished measurements before you begin.

SizeSquares AcrossSquares DownSquare Size approx.Finished SizeYarn approx. yards
XS/S/M 32 – 363  211.534.5” (W) x 23” (L)  856
L/XL/2XL 40 – 483  213.5”40.5” (W) x 27” (L)  1180

For reference, I have a 40-inch bust and I’m wearing the L/XL/2XL shown in the photo below. The bamboo yarn gives the fabric a lovely amount of stretch and drape, so I can comfortably pull the front edges together if I want a little more coverage.

Materials

  • DK #3 weight yarn; 856, (1180) yds
  • 4mm Hook (I use Clover Amour hooks)
  • Dressmaker Pins (for aligning and sewing the granny squares)
  • 2 Stitch Markers
  • Scissors
  • Yarn Needle

Yarn Choices

I used Papatya Bamboo DK for my sample. This granny square design had already been on my list to make and, when I spotted this yarn at its launch price on The Knitting Network, it felt like the perfect match.

If you’ve ever worn bamboo socks, you’ll know just how incredibly soft bamboo fibre feels!

It’s smooth to work with, produces excellent stitch definition and gives the finished cardigan a beautiful fluid drape.

One thing to keep in mind is that bamboo has a tendency to relax and stretch over time. I recommend washing your cardigan at 30°C and, where possible, drying it flat to help maintain its shape.

Papatya Bamboo DK has 11–13 wraps per inch (WPI), placing it comfortably within the DK weight category.

You can substitute another DK (#3) yarn if you prefer. For the best drape, I’d recommend a yarn with some softness or fibre blend rather than a heavier cotton.

Top Tip: Choosing a yarn with good drape will help your finished cardigan hang beautifully and enhance the relaxed cocoon shape.

Gauge

With a 4mm hook:  5 rounds = 4” x 4” / 10cm x 10cm

For the most accurate fit, I recommend blocking one completed granny square before measuring it. Bamboo yarn relaxes after washing, so checking your blocked square against the measurements in the Sizing table before crocheting the remaining five squares will help ensure your finished cardigan is the correct size.

If your blocked square is smaller than the measurement in the Sizing table, try increasing your hook size. If it’s larger, try a smaller hook.

You can also adjust the finished square size by working fewer or more rounds than stated for your chosen size, but always finish on a Round 3 repeat to maintain the correct edging.

Stitches and Abbreviations

My Aveline shrug uses these stitches:

  • Single crochet back loop only (scblo) – edging
  • double crochet (dc)
  • slip stitch (sl st)

If you need a refresher for these stitches, you’ll find instructions in part one of my stitch library.

For my UK crocheters, the table below is a conversion of basic crochet stitches from US to UK.

half double crochet (hdc)half treble crochet (htr)

How the Aveline Cocoon Cardigan Is Constructed

The Aveline Cocoon Cardigan is constructed from six oversized granny squares joined to create a rectangle.

A simple back-loop edging finishes the cardigan with a neat, polished look.

The diagram below shows how the six granny squares are joined to create the rectangle.

Assembly

  1. Once the granny squares have been joined, fold the rectangle in half with the right sides facing together.
  2. Measure the armhole opening on each side, place a stitch marker, then sew from the stitch marker to the open edge as shown below.

Joining the Squares

Arrange the six granny squares into three squares across and two squares down, then join them to create one rectangle as shown in the construction diagram.

Using an invisible seam is the preferred joining method (working under the back loops only so that the front loops pull together to create a tidy ridge on the right side and hide the seam underneath). 

You can join squares with any method of your choice.

Edging

For an edging finish that includes the sleeve opening

Rejoin yarn on RS in the first st after any corner sp

Round 1: ch1, sc in first st, scblo in ea st and ch around, join with sl st to first sc

Round 2: ch1, sc in first st, scblo in ea st around, join with sl st to first sc

Round 3 and 4:  rep round 2

Fasten off

For an edging that excludes the sleeve opening

Working in rows

Rejoin yarn on RS at top of rectangle

Row 1: ch1, sc in first st, scblo in ea st and ch, ch1, turn

Row 2: ch1, sc in first st, scblo in ea st, ch1, turn

Row 3 and 4:  rep row 2

Fasten off

Rep for bottom of rectangle

Assembly

with RS facing inwards, fold fabric in half widthways 

With the fold at the top, measure 8” on the edge from the fold and place a st marker. Sew the seam on the edge from the st marker down to the bottom of the fabric

Fasten off

Rep on other side

Turn your shrug right side out

Congratulations!  You’ve finished your shrug.
