How To Crochet The One Piece Cardigan


This cardigan crochet pattern comes in 8 sizes from S to 5XL & are worked in one piece from the top down.

You will start at the neckline, and work the yoke part of the cardigan. This is the part that has the small eyelets.

After that you will split into two armholes and the body, which are worked separately.

The sleeves are according to the pattern instructions worked in rows and turned, which means you’ll have to seam the sleeves at the end. However, if you prefer to work the sleeves in turning rounds, to avoid seaming, that’s a great option. All you have to do is to slip stitch at the end of each row, and then turn.

Most of this one piece crochet cardigan pattern uses basic crochet stitches. Half double crochet stitches are the main feature, and chains create the eyelets at the top of the cardigan.

The most advanced stitch used is the foundation single crochet to start the cardigan, but it’s possible to swap that for chains if preferred.

Finally, you will have to work half double crochet stitches together. These are described in detail under the heading “stitches used in this pattern”.

Yarn For The Crocheted In One Piece Cardigan


The suggested yarn for this crochet cardigan pattern is Galler Yarns, Prime Alpaca. It’s a beautiful alpaca yarn.  

What made me choose this particular yarn for this crochet pattern was the first & foremost the softness of it, but the lovely colors to choose from didn’t hurt either.

Find it here.

If you prefer using a different yarn, make sure you test your gauge before you start crocheting.

How Long Does It Take To Crochet That?


How long it takes to crochet something varies depending on your skill & how fast you crochet. But that isn’t a helpful answer is it?

Well, I’ve developed a yarn calculator to help you get the answer to this question.

It will help you calculate exactly how much time you’ll spend crocheting a project.

All you need to know is how much yarn you will use on the project in either meters, yards or skeins. Then crochet your test square & time it.

Calculate how long it takes to crochet that.

Crochet Pattern Notes


  • This crochet pattern is written in US terms (more details).
  • All measurements given are unblocked.
  • Note that measurements are given as exact as possible. But crochet tension & technique might give variations in the result, that changes from person to person.
  • Read pattern instructions carefully before beginning to make sure you understand everything. It might save you hours!
  • Make a swatch that measure at least 10 x 10 cm / 4 x 4 inches using the stitch the gauge is given for. If your swatch matches the gauge, you’re good to go. If the gauge is wrong, you might need to change your hook. Go up in crochet hook size if your stitches are smaller & go down in crochet hook size if your stitches are bigger (more details).
  • Check yarn info if you want to find an alternative or test your yarn against the gauge (more details).
  • This pattern is written for 8 sizes, where the different sizes are given in parentheses like this: S (M) L (XL) 2X (3X) 4X (5X). If just one number is given, it applies to all sizes. I recommend that you highlight or circle the size you’re making before you begin to make the pattern easier to follow. Size adjustments are added under “Size & Measurements”.
  • At the end of each row, the stitch count is given in parenthesis.

Sizes And Measurements


One Piece Crochet Cardigan Pattern

Size Notes

  • This pattern is written to have a standard fit, that means about 5-10 cm ease.
  • Take bust measurements to find the size that fits the best.

Size Adjustments

  • Note: Any size adjustments affect yarn usage & you might need more/less yarn than suggested.

Yoke:

  • Starting the yoke: If you want a smaller/bigger opening for the head. Reduce/increase the starting FSC in increments of 6 st. Note: This would change the stitch & row count for the yoke throughout.

Body:

  • For all sizes: Adjust length by adding or reducing rows at the end, before starting row 51.
  • Adjust width by making the yoke smaller or bigger. Alternatively, add more FSC stitches on the first row of the body.

Sleeves: 

  • The sleeve pattern is written to have a balloon shape at the wrist, that means they have the same width until the final row. If you feel the sleeves turn out to wide, decrease a few stitches at the beginning of a few rows by crocheting 2 hdc stitches together. 
  • If the final row makes the opening for your hands to wide/tight, hdc2tog instead of 3 to make it wider, hdc4tog instead of 3 to make it tighter.

Stitches Used In The Crochet Cardigan Pattern


You will need to use chains, single crochet stitches, half double crochet stitches, double crochet stitches,  & foundation single crochet.

Foundation Single Crochet Stitch (FSC):

Written description:

Step 1: Ch 2 st.

Step 2: Insert hook into 2nd ch from hook, pull up a loop. Yo and pull through first loop (making “chain”). Yo and pull through both loops on hook.

Step 3: Insert hook into previous “chain” you made (It should look like you go through a resemblance of a “normal” st, with 2 strands of yarn), pull up a loop, yo and pull through first loop (making “chain”). Yo and pull through both loops on hook.

Repeat step 3 until you’ve made enough stitches. *2nd ch in step 1 makes 1 st, step 2 makes 1 st & every time step 3 is repeated you make 1 st.

  1. Hi,
    This is my first cardigan I’ve ever made, I love it & I’m really loving how easy you’ve made the pattern to follow.
    However, upon making the sleeves you have put attach yarn in one of the middle fsc stitches, “STITCH 3,4,5…”
    I’m not sure what you mean by stitch? Is it sc? Or chain? . Sorry for the dumb question….
    Thanks again for your amazing work, it is truly appreciated.
    Kind regards,
    Trudi, UK

  2. In the rows that don’t apply to my size, do i skip to the next row? After the yoke section I can’t get the instructions clearly. Is it telling me to HDC all the way around and FSC under the arms??

    Reply
    • You do “yoke”, until your size isn’t mentioned anymore.
      Then you jump to “Finishing Yoke”.
      Then after that all sizes should do all rows on both “Body” & “Border”.

      The first row on the body, splits the stitches from the yoke into 5 sections: 1. First front. 2.Armhole (where you crochet FSC). 3. back. 4. Armhole (where you crochet FSC). 5. Second front.

      Hope this helps.

  3. I really like the pattern, however, I was wondering if I used a #3 yarn with a G or H hook would I be ok to go up one size. I usually take a XJ because I like the room. Thanks for all your patterns and your help. Jackie

  4. Hi – I cannot get the stitches to add up on row 1 of the body. I have the right # from row 35 (233)
    But row 1 just does not add up – it says I should do: HDC 38 + FSC 12 + SK 40 + HDC 77 + FSC 12 + SK 40+ HDC 38 = 257.
    It says I should have 177 stitches left but if I take the worked st – 177 and add the sk sts of 80 it adds up to 257 but I never had 257 at the beginning. So confused!!
    Doesn’t matter what I do – I have tried doing less in one part or the other etc but to no avail. I am at a loss as to what I am doing wrong. Any help would truly be appreciated please and Thank you

    Reply
      • Hi Janne – still confused sorry – if I skip those stitches I only end up with 153 not 177. I only started out the body with 233 st which it says I should have after finishing row 35.
        Sorry for not understanding 🙁

  6. Hello!!
    Just a question:
    In row 1 of the body, when it says to do 18fsc, is it extending off the piece and then joining back on afterwards? This is what makes the armhole?
    Thanks for the lovely pattern. Making this for my grandmother!!
