Free crochet pattern: Granny square cocoon cardigan

I receive commissions for purchases made through links in this post.

One of the great things about the granny square cocoon cardigan is that it can be made in just three simple steps by anyone who has mastered basic crochet skills: chain stitch, slip stitch, single crochet and double crochet.

Another great thing about this pattern is that it’s so forgiving that gauge doesn’t matter. To get the correct size, all you need to do is make your granny square at least half as tall as the intended wearer of the cardigan, plus an extra inch or two. That’s step one.

To get the correct size, all you need to do is make your granny square at least half as tall as the intended wearer of the cardigan, plus an extra inch or two.

Step two is to fold the granny square in half and stitch up the side seams, leaving openings for armholes. Step three is to add a border of six rows of single crochet around the armholes and the front opening. That’s all there is to it!

The sample cardigan shown here, intended to be worn by someone who is 5’4″ (64″) or shorter, is based on a 33″ granny square made from 4 skeins of Lion Brand’s Heartland yarn, which works particularly well for this pattern. (It comes in numerous colors; I used the color “Redwood.”) To make a cardigan for someone taller than 5’4″ using this yarn, I recommend getting 5 skeins.

Here is a two-minute video showing the pattern basics. The written pattern follows below.

Pattern: Granny square cocoon cardigan

Materials you’ll need:

  • 4 or 5 skeins of Lion Brand’s Heartland yarn, depending on intended size of cardigan, or 1000-1250 yards of a medium weight (#4) yarn of your choice
  • Size J crochet hook
  • Scissors
  • Measuring tape
  • Yarn needle

Stitches used

  • Chain stitch (ch)
  • Slip stitch (sl st)
  • Single crochet (sc)
  • Double crochet (dc)

To connect new skeins of yarn, I recommend using the Russian Join, which reduces the number of weave-ins required. Watch this video for a quick tutorial:

Step 1: Crochet a BIG granny square

Ch 6 and join in a ring with sl st.

Round 1: Ch 3 (counts as 1st dc here and throughout), 2 dc in ring, ch 2, * (3 dc in ring, ch 2) 3 times, sl st in top of starting ch 3.

Tip: Lay yarn end along ring and crochet Round 1 over it for an effortless weave-in.

Round 2: Ch 3 and turn, (2 dc, ch 2, 3 dc) in ch 2 space to form a corner, (ch 1, 3 dc, ch 2, 3 dc) in 3 remaining ch 2 spaces, ch 1 and sl st in top of starting ch 3.

Round 3: Ch 3 and turn, (2 dc in ch 1 space), (ch 1, 3 dc, ch 2, 3 dc) in each ch 2 space in corner and (ch 1, 3 dc) in each ch 1 space on side, ch 1 and sl st in top of starting ch 3.

Repeat Round 3 until square reaches desired size.

Final round (“binding”): Ch 1 and turn, sc in each dc and through each ch 1 space on sides; in corners, 4 sc through ch 2 space; sl st in starting ch 1, cut 6” tail and fasten off.

Do 4 single crochet in chain-2 corners.

Step 2: Stitch together sides forming armholes

Fold square in half with right sides together to form a rectangle, taking care to align 3 dc clusters and ch 1 spaces to the clusters and spaces on the opposite side.

Note: If you made your granny square using the above instructions in which you turn the work after every round, both sides will probably look pretty much the same, and you can pick whichever side you like best to be the “right” side.

Beginning 7” from fold, single crochet through all loops of “binding” (final round sc) to end of side and through first 2 ch of corner only.

Note: Beginning 7” from fold creates a 14” armhole which will fit most. If necessary, the armhole size can be adjusted smaller or larger by starting the side seam closer to or farther from the fold.

Cut 6” end and fasten off.

Repeat on other side.

Step 3: Add borders.

For the front opening and both armholes:

Round 1: Join yarn with sl st in sc “binding” near one of the side seams made in Step 2, ch 1, sc in each sc of “binding” until you reach ch 1, sl st in ch 1.

Tip: Crochet Round 1 over yarn ends left from binding and side seams for effortless weave-ins.

Rounds 2-6: Ch 1 and turn, sc around front opening until you reach ch 1, sl st in ch 1.

Cut 6” end and fasten off.

Weave in ends. (If you crocheted over all previous yarn ends, and used the Russian join to add new skeins of yarn, you should only have three ends left to weave in.)

    • Mara – I have not made it in that size, but this is a loose and forgiving cardigan and I see no reason why you shouldn’t be able to. My advice is when you’ve made your square, before you stitch the seams, pin them and try it on, and then make it bigger if necessary (have extra yarn for this). You may want to adjust the armholes also. If you try it, I’d love to know how it works out!

      • No, I have not yet seen one I know for sure to be size 3X or larger. I HAVE seen one made for a woman who is 6 ft tall, and from the photo it looked like it was at least a size 1X or 2X — and it looked really good. The person who made it said she used nearly 2 whole Caron Big Cakes. Sorry I can’t be of more help.


      • This will be my first try making anything wearable. Im a little nervous starting out. I’m making this for my 16 yr granddaughter. I will let you know how it turns out. Wish me luck😊


    • YES! How you adjust the pattern depends on your measurements. I’m short and round, So I have to do a rectangle or it’s too long. If you’re 5’5 or taller, just measure the largest part of yourself( hips, waist, or bust), subtract 6″, and that = the size square you need to make. My square, for a 3X is usually 54″ (+ a 3″ collar/border). That just fits my taller 3X’s. You can always add extra rows of trim to make it fit, too, in case you misjudge. Do an increase (2 stitches in the same stitch every 10t stitch) on the first row, then repeat the rows for the boarder pattern you used.


      • I’m also short and round! I’ve made a square bigger than half my height and its too big around my neck and not big enough to go around my body. I wondered if making it a rectangle would work. So thank you for confirming it does!


    • Dortha, om the top row ,where the address bar is,do you have thre dots on the top right of the address bar??? If you click on that a drop will open up and there should be options,and one SHOULD be SHARE , its there that you can copy or send it to your email or FB messanger…..
      I hope this has helped you to get your copy of this!!


  1. Many thanks for this pattern. The instructions are so beautifully explained. Hooking it slowly due to carpel tunnel but know this is achievable. Can’t wait to see what you come up with next 🙂


    • Dee – I’ve never done it myself because I prefer three-quarter sleeves, but I have seen some people create a sleeve after sewing the sides together to form the armholes, by continuing the granny style stitch around just the armholes until they reach the desired length. Hope this helps!

    • Linda – I’ve never tried bulky yarn – I’ve always used 4 weight yarn – but I don’t see why you couldn’t make this with bulky yarn and a larger hook, as long as the resulting fabric is pliable and not stiff. If you try it, let me know how it goes!

  3. Hello Thank you for sharing your lovely pattern. I have a question? How do you stitch the seams? Sorry to be so thick. First pattern I have followed.


  4. Confuse not much of pattern reader – I have my square and ready to do sleeves – do I single crochet to the end to close the side and rotate to come back up to do the six rolls first


  5. I stumbled on this gem on Pinterest, it got me so excited! It is 6:15 in the morning in Botswana, I can’t wait for the stores to open so that I can get my wool and get started!


  6. This is my first cardigan and love how easy your pattern is to follow especially for a new by like myself. I have used wool that fades in and out of white, Grey’s and black. Can’t wait to try it on. I’m sure it will be my first of many.

  7. I guess it is optical illusion but the pic messed me up a bit despite the instructions because your square looks like a rectangle lol however I am doing it right now and so far it seems ok. Thank you so much for posting this.


  8. I am a 3X and I will be making this for myself. to adjust for my large stomach and arms, I will make the granny square several inches larger than 1/2 my height. (I am starting with a full foot,12″ larger, that way, I will have a little ‘wiggle’ room)
    Thanks for such an easy to follow pattern! (sorry, I have no way of taking a picture and posting)


  9. Wow I love this cardigan. Thank you for the pattern it looks so easy. I’m 5ft 2 so I’m going to follow your pattern exactly to see how it turns out, I’ll let you know. I’m off to the shops to buy the yarn. Now to decide what colour to buy, something summery I think 🤔


    • 5 ft = 60 inches, half of that is 30 inches, so going by my pattern I would advise 31 or 32 inches. You can always pin it and try it on to be sure before moving to the next step.


  10. I made this but now I would like to try it with Crochet thread #10 do you think this will work as long as I get
    the granny square big enough.


    • Peggy – I haven’t worked with #10 crochet thread myself so it’s hard to say. My only concern is that the resulting granny square might bee too lightweight to wear properly. If you try it, let me know. Good luck!


  11. This is the best pattern I’ve found for shrugs, simple and straightforward making it a breeze to put together! I just finished it except for the collar borders and bottom and I’m amazed at how great it fits and looks on, thanks so much and keep these great patterns coming, yaaaaaay!


  12. Do I make the arm holes borders and main body border while the right sides are still facing eachother after making the armholes or do I turn it out right and then add them? I am new to crochet and thought this was an easy first wearable. I just don’t want to mess it up!!


  13. Hello Sam, this is the fist time that I have emailed you so to let you know who I am; My name is Heather and I am from New Zealand, it’s just after 3am here and I was looking through you tube and saw your pattern, now I’m going to try it. I have only over powered the crochet hook in the past couple of months so I’m looking forward to seeing how this works for me; I’m hopeful !! will let you know when it is done.
    Blessings from NZ.
