Sleep sack for preemies or newborns, free crochet pattern for Painted Canyon Cardigan

Newborn Sleep Sack Free Crochet Pattern

Of course, we have sizes that the whole family can wear, this is the free pattern for the newborn sleep sack and I’ve included instructions for preemies as well.

If you are expecting (congrats!!), if you have a newborn, or if you are breastfeeding (or trying to or planning to!), may I suggest this article I wrote about my year-long experience of exclusively pumping for our youngest? Sometimes I can’t believe I lasted that long exclusively pumping, but I’m glad I did. Our oldest was bottle-fed (because of his undiagnosed health issues). Feed your baby however you like, but if you need help producing more milk, this article may help! 😀

Adding edging to a preemie size sleep sack

Row 1: Ch-1, hdc in the end of each row up to hood, around the top edge and down the other side making sure to place just one hdc per row as in this tutorial.
Row 2: Ch-1, hdc in first * fphdc in next, bphdc in next * repeat between ** around to end, hdc in last st.
Rows 3-4: Ch-1, hdc in first, fphdc around previous row’s bphdc (to create ribbing), bphdc around next fphdc. * fphdc around next, bphdc around next * repeat between * * to end, hdc in last st.
Fasten off and weave in tail.


Disclaimer: You could also add short chains to the sides to use as ties in order to eliminate the risk of choking as the baby ages. This sleep sack is intended for use with brand new babies that have no interest in shiny things such as buttons. Use your own discretion as it pertains to closures.

Fold up the bottom half of the sleep sack and decide where to place your buttons. You’ll place the buttons/ties on the top half of the sack so that you can fold up the sleep sack and use the buttons as closure. If you choose buttons that are about 3/4″ in size, they should fit through ANY of the holes on the edging of the corresponding/top side. This also makes the sleep sack adjustable as the baby grows! Bonus!!

  1. I was wondering about the finished size. For rows 1-92 in the newborn size (main body, no hood), what is the height and width?
    1. The overall length (before sewing hood and folding) will be approximately 33" for preemie and 40" for newborn.
  2. I’m having an issue with the count, I do the 41 and chain in the second I get 39 stitches. So shouldn’t the stitch count be 42?
    1. Hi Lizzie! That was Hobby Lobby's I Love This Yarn...I can't remember the color exactly (and they may have discontinued it) but Mixed Berry is the closest I can find (and may be it...lol)
  3. Hello, I’m a little confused about the stitch marker part of the directions , it talks about “if an odd number stagger them so that they always line up”. If there are 40 stitches how would there be an odd number ? Am I misunderstanding something ?
    1. Hi Carrie! Since we are doing 8 rows and decreasing by 1 every row, then every other row would have an odd number of stitches. So, for example, row 93 will end with 39 sts after the decrease, so on row 94, you would start your decrease in the stitch to the right of your marked center stitch...then on the next odd stitch row you are working into (row 96) you would start the decrease in the marked center stitch and finish it in the stitch to the left...this pattern staggers those decrease stitches so they line up better in the center. Does that make sense?
  4. I would like to try the sleep sack Similar to the others who have commented, it would be awesome if there was a video, step by step, for us to follow. This is so adorable, is it easy for a beginner?
  5. Hi. I've started making the sleep sack. I measured that it will be 13" wide. That doesn't seem wide enough for a newborn. Am I doing it correctly? How wide should it be?
    1. Hi Cindy! The newborn size should be approximately 14" wide before adding the edging...and the edging will add another 3-4 inches.
  6. First off I love the sleep sac pattern! Is so stinking cute. I’m having a problem figuring out the edging. I’ve never done fphdc or Bphdc but figured that out online. Now my problem is Row 3, I can’t seem to understand exactly where to insert my hook. Is it under the top V stitch’s or below them into the previous row of stitching?

  8. You are a dear to give us such a sweet free pattern and answer all the questions so nicely! God bless you!
  9. I am getting ready to start on the first row of the edging but trying to figure out how I am supposed to start/attach the yarn for the first chain? I'm thinking I need to take a break and come back but want to get this project finished. Lol Lisa
  10. Hi I am trying to follow your pattern but I cant figure out where the hood is because at the end of the newborn it says leave off to attach the hood but I cant seem tk find the pattern for the hood
    1. Hi Angel! The hood is the last several rows of the pattern...rows 93-100 are the shaping of the hood. You will fold the top rows together and use the long tail to sew them up to finish up the hood. Hope this makes sense!
  11. Hello, I'm new to crocheting and I'm trying to follow your pattern to make the newborn sleep sack for my little one that will be here in October. For me your pattern is a bit confusing and I'm not familiar with the Fdhc, is there a easier way to make this with simple chains and stitches so noobs like me can understand how the sleep sack is made?
    1. Also I want to try to customize this pattern to allow baby to grow up to 6 months, as well multiple use in crib, carseat and stroller.
    2. Fphdc stands for front post half double crochet. It's a little hard to explain without showing you, but basically it makes a ribbed kind of pattern. Instead of inserting your hook under the chain, you insert your hook around the full previous stitch and then preform a half double crochet. There are a lot of videos that can show you visually how to do it. I've used it in a lot of my own patterns and projects and it looks really cute on my sweaters and stuff. I hope you're enjoying crocheting!
    3. Fdhc is foundation half double crochet, the pattern gives the alternative to start with a chain and hdc. Basically this is a long rectangle where the top is folded together to create the hood. Once you begin, go step by step and you’ll see it makes sense.

  13. This is an adorable pattern! Thank you for sharing this design☺️ When it comes to the edge work, how do I attach the yarn to start the edging? Is there is video tutorial somewhere? Thanks!
  14. Finishing up the third one of this pattern, I love it. Have a suggestion though. I made crochet buttons instead of using wooden buttons.
    1. Another option for anyone who's interested: I make buttons out of wine bottle corks and they are so cute and original. I just cut them and shape them with a dremmel tool and use a drill to poke the holes. You can paint them if you want to, but be sure to use baby-friendly paint! I don't exactly know the size of buttons it makes, but it's cute anyway. If you use them on the older-child patterns though, do be aware that they will be chewed on, so clean them really really well.
  15. Hi love this pattern! Can I have the finished pattern's dimensions please. The length in particular before the hood. Thanks so much.
    1. Hi Shellie! I have a companion video for the painted canyon cardigan that should help. At about the 25:50 minute mark is where I sew to create the hood. Here is the link: https://www.youtube.com/watch?v=061ASkM1GB8
  16. Hi there, have already made this once and it was stunning! Thanks so much for sharing. For the next one, I've a really bulky yarn - would single crochet work instead of hdc? Thanks heaps :-)
    1. Hi Nicole! Bulky with single crochet might work...I would work up a gauge swatch and if it's close to my gauge, I would try it!
    2. Can you please give the overall measurements. Width of sack, length of sack, length of hood. I would like to mix it up a nest do different stiches sometimes. I crochet for Newborns In Need and 0lan on making several of those. Thank you so much. Love this projject.
  17. I need help regarding the hood area. How do I do it? Right now it doesn't have a curved shape. Need help quickly. Thank you
    1. Hi Valerie! The hood should be basically a flat piece until you sew the top together which will give it the hooded curve. I have a video for a different pattern but has the same hood construction...you can find that here at about the 25:50 minute mark is where I start sewing the top of the hood together: https://www.youtube.com/watch?v=061ASkM1GB8 Hope this helps! If not you can send me a pic to my email or to the Heart Hook Home facebook page and we can try to get it sorted out.
