Baby Sleep Sack Knitting Pattern

This baby sleep sack is a fun knitting project and the perfect little baby gift for a special little one in your life.  And it's a perfect baby knitting pattern if you love to knit cables.

When I discovered I was going to be a grandma again I decided to knit this baby sleep sack with the OXO cable all around it. It was fun too!


Baby sleep sack

A baby cocoon is a great way to swaddle your little one.  And I made it with the idea of being able to swaddle baby.

That's why it's not overly wide but rather just right to swaddle a baby so he/she feels snug and secure.

If you're comfortable with knitting in the round and you enjoy knitting cables then you're going to love knitting up this baby cocoon. 

The cable stitching is worked on every 4th row with the rest of the rows being simple knits and purls.  

In many ways it's pretty simple and a fun knitting project. It's also a nice change and maybe even a nice challenge for some of you.

The baby hat pattern is also knit on circulars and then closed at the top with the Kitchener stitch. I’ve provided a knitting video a little further down showing you how to work it.

I hope you enjoy this baby sleep sack knitting project as much as I did creating it.

Baby Sleep Sack Pattern Details

Required Skills: Knit, purl, cable knitting, circular knitting

Sleep Sack Circumference: Approximately 17 inches not stretched and at least 24 inches stretched. Length: 21 inches.

Hat Size: To fit head circumference up to 16 inches and is very stretchy

Gauge: 5 sts per inch over Stockinette Stitch

Needles: US 10 (6.00 mm), 16 inch circular knitting needle

Materials:  4 - Medium (Worsted) Yarn. I used Cascade Pacific (60% Acrylic, 40% Superwash Merino Wool) Each ball is 190 yards / 173 m and I used almost 2 balls for the sleep sack and a new ball for the hat.

Abbreviations:

K, k = knit

P, p = purl

cn = cable needle

sl = slip

st, sts = stitch, stitches

Rnd = round

YO, yo = yarn over (bring yarn to front of work as if to purl)

K2tog, k2tog = knit 2 sts together

Notes: I used two cable stitch patterns in the baby sleep sack, one is the XO cable pattern or hugs and kisses cable stitch.  

The other cable stitch was from my knitting cables page and it's a simple 4 stitch cable stitch pattern. 

The OXO cable pattern is worked over 16 rows and I knit it 7 times to reach 21 inches in length. It works up pretty quickly once you’ve gone around a couple of times.

Weave in ends. Make an I-cord tie and thread through eyelets at bottom of sack. You could also use ribbon if you prefer. Add little pom poms if you wish or just leave it plain.

 Matching Baby Hat Knitting Pattern

Notes:  The baby hat knitting pattern is also knit in the round and closed at the top using the Kitchener stitch.  This was really fun to knit.

If you don't know how to do the Kitchener stitch I've included a video below to help you.  

Or if you simply don't want to use the Kitchener stitch you could bind off all stitches at the top and seam it. 

Whatever works for you. I've become a fan of the Kitchener stitch as it is a completely invisible seam and it's also kind of fun to do. 

I worked the 16 row XO cable pattern once for the hat and the rest was simply knit. 


Cast on 80 stitches and join in the round being careful not to twist sts.

Knit 6 rounds, then proceed as follows:

Rnd 1 - 3: P2, K8 around

Rnd 4: *P2, slip next 2 sts to cn and hold in back, K2 then K2 from cn, slip next 2 sts to cn and hold in front, k2, then knit 2 from cn, repeat from * around

Rnd 5 - 7: As row 1

Rnd 8: *P2, sl next 2 sts to cn and hold in front, K2, then k2 from cn, sl next 2 sts to cn and hold in back, k2, then k2 from cn, repeat from * around

Rnd 9 - 11: As row 1

Rnd 12: As row 8

Rnd 13 - 15: As row 1

Rnd 16: As row 4

Rnd 17 and onward: Now just knit around until hat measures 7 inches.

Two binding off knitting choices:

1. Kitchener Stitch – use this stitch for binding off and creating a seamless hat. Knitting video is below showing you how to knit Kitchener stitch.

2. Bind off loosely and seam the top of the hat.

Finish Knitting

Weave in ends and add pom poms or tassels or whatever your preference is.

Wrap up your precious little one and enjoy!
