Cozy Infant Cardigan Crochet Pattern (Size 3 – 6 months)

I know what you’re thinking… “come on Ashlea, another crochet cardigan series??” Yes, really. With the designing of the Painted Canyon Cardigan (and its horizontal rows) I decided that I needed a cardigan pattern using vertical rows as well. So, here we are, working our way up from the 3 – 6 month infant cardigan pattern to full grown men’s sizes!

With this cardigan series I’m going for the “professor” feel. For the adult sizes I’ll add elbow patches (you could instead use felt for the smaller sizes) and for the larger sizes we’ll call it the “Cozy Coed Cardigan”. These first few itty-bitty sizes will simply be called Cozy Infant Cardigan. Cool?

Not gonna lie, I’m feeling daunted by the task of creating bunches of new sizes, but when I look at that adorable little puddin’ face sporting this adorable new cardigan? Meh, I’ll suffer through it. 😉

  1. I’m curious about something; I’m wondering why the back and (a single) front side are completed first (rows 1-33) and then you reattach to this and create the other front side. Wouldn’t it be easier to complete the entire piece in one? I’m making baby gifts and thinking I’ll make multiples of this but (also) thinking I’ll complete both fronts and back in one step. (Am I making sense?)
  2. The instructions are just vague enough to cause issues. I have to go back to sort out the shoulder seams due to the way the instructions are worded. I would suggest more photos in the future to show people what you mean at major steps. A clear written pattern is the difference between me paying for more patterns vs just trying to finish this one and survive.
  3. Hi. I always struggle with gauge. Is the length a little less than 12 inches? Just wondering if I can adjust because I keep ending up with not enough and when I go up hook sizes to meet stitches, my rows go up too much.
    1. Hi Joelle! Since this pattern is worked vertically, stitch width will determine cardigan length which on this size would be about 11".
  4. This is an awesome pattern. It's hard to find a baby pattern that uses worsted weight yarn. I had some Caron Simply Soft that I wanted to use up and this pattern fit the bill.
  5. i was wondering if i could get a printed version of this pattern . cozy infant in size 3 months. if there is a place to purchase it, where will i find it?
    1. Hi Deb! The childrens sizes are available as a printable pdf on Ravelry which can be found here: https://www.ravelry.com/patterns/library/cozy-classroom-cardigan

  7. Hi. I’ve made this cardigan in size 3-6 months following the pattern but can’t see where and how to do the buttons. Can i add them in later? If so, how? Thanks!
    1. Hi Georgina! You can add buttons at the end...just sew them onto one side of the front edging, and they should slip through in-between the stitches on the opposite side. Hope this helps!

  9. Could you please make a video tutorial for this. I really want to make it but need to learn by video. It is adorable.
    1. Hi Judy! I have a companion video for the adult version of this pattern which can be found here: https://www.youtube.com/watch?v=8fCfUOb4oFw
  10. I just sewed the shoulders together - are they done separate or straight across? I noticed one comment sent all the way and another said leave 3 rows open. Plus do I fasten off after the shoulders part? Now I am totally confused how and where to start the edging collar? Thank you.
    1. Just making sure I understand the pattern directions about the sleeves on the size 3-6 months size. Do you sew the seam together afterwards or will it be connected while crocheting them
      1. Hi Chris! The sleeves are worked in continuous rounds (in a spiral with no joining) so there is no seaming required for the sleeves.
  11. Hello, I need need some help. Do you have pattern or skitch a of the pullover? And a detail of the diagram? Please, I m not good of the english, it would be better if I can see the diagram or the others. Thank you.
  12. Help please. I'm a little confused, at Sew shoulders together. Do you have a picture of which way to folder the panels to sew the shoulders. Can't seem to visualize his it's supposed to go. Thank you
    1. Hi Crystal! No, the next size up is 12 month. The finished measurements are listen in both patterns to help figure out which size to make. Hope this helps!
  13. What size buttons did you use for the 3-6 month cardigan? Love this pattern! This is the first sweater that I have made am I excited to give it to the recipient!
  14. I am sewing the shoulders together now but I’m not sure if you sew them all the way across or leave an opening? I feel like the cardigan neck line will be too tight if I see all the way across the top.
    1. Hi Monique! Yes, you will sew them all the way across. Adding the edging/collar will help open up the neck area. Hope this helps!
    1. Hi Laura! With your cardigan turned so the top is to your right, you will be working into the bottom of your foundation row. Chain 13, skip the 1st 13 sts on that foundation row and work your 1st hdc into that 14th stitch...then continue working hdc's across the remainder of the row. At the end of the row you will have 13 chains and 17 hdc giving you 30 stitches total. The picture above the pattern instructions for this part shows the chain 13 made with the hook in the 14th stitch to give you a better visual. Hope this helps!
  15. I've completed row 33 and I'm stuck. I've read all the comments and still lost. Did anyone else make this and take photos of the process they can post? Thanks!
  16. I LOVE this pattern! It is well-written and easy to follow once you get the idea how the 2nd front side continues on the back. I'm expecting my first grandson in September and have made 2of these cardigans so far to match crocheted Ugg boots and converse tennis shoe and matching hats. This cardigan goes with everything! Thank you so much for sharing. I rated the pattern and meant to giv e 5 stars but my finger slipped and 4 appeared instead. My apologies. Thank you again so much!
    1. Hi Barb! Congratulations on the upcoming grandbaby. I am so glad you have enjoyed the pattern! Thank you for the rating =)
  17. My gauge is off!! I tried several different yarns. With a 6mm hook and a medium yarn my gauge is: 11 hdc=8 cm 10 rows: 11 cm If I go up a hook size, the length increases with the width. It's not a square, it's a rectangle no matter what size hook I try. Should I try the pattern in single crochet instead of hdc to make it more even?
  18. Hi there I love this pattern it is my first cardigan I am making what part is the shoulder I'm confused as to where I need to sew lol Tia
    1. Hi Catherine! The top of the cardigan is sectioned off into 3 panels (a center/back, and 2 front panels). You will fold the 2 front panels in onto the back panel and sew the top of the front panels to the top of the back panel...this creates the shoulder and armholes. Hope this helps!
    1. U make first the back and half of the front. After u make the other half front. Attach them. Make the neck bit. And the sleeve 2 times make the button and done. I just made it a second ago. Just follow everything row by row and u gonna see it when the first 33 row is ready. To be honest i don't understand it first either but when i did the first 33 row it made it clear how gonna look like. I hope that's can help u
    2. I had a hard time understanding after rows 1-33. See if this helps: When done with the beginning rows 1-33, the slit to the right (in the photo) is the right armhole. It will be folded over in a bit, to sew shoulders together. Also In the photo, it is hard to see but she is sewing the front (other front) to be attached to the left side of the sweater. The chain 13 is the left armhole. Then the 14 hdc is sewn on that left side. When done with the 11 rows for this "other front" (I needed 12 for good closure) it will be folded over, as well, to sew left shoulder together,
    3. Hi Ruth! After you complete rows 1-33 and fasten off, you will start to make the second front panel. To do that, you will chain 13, HDC in the 14th stitch on the other side of the main body of the cardigan (mirroring the 1st armhole/front panel) and HDC in each remaining stitch across the row. So you will have 13 chain stitches and 17 HDC after completing that row. Hope this makes sense!
      1. Thanks for awesome pattern! I was doing great until I reached the edge /collar section. Now I'm super lost. Do you have any video tutorials or more pictures? More pictures before the major steps would be so helpful but a video would be even better!! I can't get stitches to add up to your stitches. I read a comment that one step should be 19 instead of 29 as stated? Was this fixed online ? I'm so confused!
    1. Hi Justine! The buttons should slip in between the ribbed stitches of the edging on the opposite side. Hope this helps!
    1. Hi Michelle! I would just go down a hook size and maybe go with a 3 weight yarn, then follow the 3-6 month pattern. Hope this helps!
    1. Hi Melody! The 3-6 month only takes about 200 yards, so you could probably do it with one skein.
      1. I would say closer to 300 yards. I had a 252 yard skein and ran out just before finishing the 2nd sleeve and still had the bottom edging to do. My gauge was correct, so not sure what happened.
    1. Hi Rashami! You could do it with the H...I would probably go down to a 3/dk weight yarn too. Hope that helps!
  19. Hi I sent a question about this pattern earlier and I was just checking for a reply, is this an active account still? Thank you for a reply
  20. Hi I am loving your pattern! I have a question please, as I'm working up the pattern, I am working on the edging, I have just begun and have done the 27hdc, 2hdc in next, hdc in next, hdc in next, but when it says to hdc2tog in same and next st ( the shoulder seam sts) I get confused, does it mean to do the hdc2tog in the same stitch of the last hdc? And to do hdc2tog in the next stitch, which is the shoulder seam stitch? I hope I have not confused you with my question!!!
    1. Hi! Yes, you'll do one hdc in the shoulder seam (on the front of the cardigan) and then hdc2tog straddling the two corner stitches, and then hdc in the same st (on the back of the cardigan). Does that help?
  21. I love this! Thank you for creating a lovely pattern for boys, they are so difficult to find. As I was looking at this, my husband says "you can make one of those for me". He never offers to wear anything I make, LOL. So... are you making men's sizes too? :-) If you are, he wears a men's size small or medium... just in case. (big cheesy grin here)
  22. Hello! In the Edging/Collar section, Row 4, it says to hdc in 1st st, then fphdc , bphdc 9 times, giving 27 sts so far. Wouldn’t it be 29 sts so far? I’m confused. Thanks!
    1. Hi! Yes you are right! Yikes! Thank you, I'll update it! I may have confused that number with the next size up. Ugh. Thanks for letting me know!
    1. Hi, when are you going to post a new born size. I am anxious to make the smaller size. Great patterns. Thanks
  23. I am just a little lost. When seeing shoulders together - do I sew all the way across or separate Then where it says Edging/collar Where yarn is attached - mine is bottom right at the front so do I go up?
    1. Hello! Yes, you can go up from the bottom right. You'll sew the shoulders just for as many rows as are on each front when lined up to the back. I believe I will make another of these cardigans to take more, better photos of the process.
  24. Thank you for sharing this beautiful patern. All my younger friends have baby boys ranging from 1-24month. So now I am busy crocheting tiny sweaters
  25. Do you have instructions for newborn size? Would love to do your sweater for my new grandson to wear home from hospital. Newborn-3 months actually. Thank you
