Chunky Irish Moss Stitch Sweater

The Yarn I Used

I made the sweater using The Wool (from We Are Knitters) in the color spotted grey.

This yarn is very warm to wear as it is 100% Peruvian wool.

The yarn weight is number 6, super bulky/super chunky/18-20 ply.

Notes on sizing

In the photographs, the model is wearing a small size (S – 32 inches/80 cm).

The sweater is very oversized so the small size will also fit a medium-sized person and so on.

There is no need to make a size up if you think your size might be a snug fit.

The pattern is written for all sizes starting with the small size – with changes for different sizes listed in all necessary places.

To follow the pattern more easily, circle or highlight all numbers pertaining to your size before beginning.

Gauge – 6 sts x 8 rows = 4×4 inches /10×10 cm In stocking stitch – with the 15mm (US 19) needles.

  • Circular needles are used to accommodate the number of stitches.

Stitch Pattern Notes

1 x 1 ribbing = K1, P1 (It is obtained by alternating knit and purl stitches in one row and “knitting by pattern” in every next row.

This means that we make a knit stitch when the previous row stitch looks like V and make a purl stitch when the previous looks like a bump.)

Cast On: even number of stitches.

  • Row 1 (RS): (k1, p1) till the end of the row.
  • Row 2 (WS): (k1, p1) till the end of the row.

Repeat these two rows.

Making Up

Tutorial

You can find a mattress stitch tutorial here.

Tip

It’s best to work on a large surface (like a dining table or desk) so you can lie the pieces out flat and see where you will be seaming.

Step 1

Seam the back right raglan sleeve seam using the mattress stitch. Make sure the right sides are facing you.

Step 2

Join the right sleeve seam to the front raglan seam using the mattress stitch.

Make sure the right sides are facing you.

Step 3

Join the left raglan sleeve seam to the front raglan seam using the mattress stitch.

Make sure the right sides are facing you.

Step 4

Leave the left-back raglan seam open for now.

With the RS of work facing you, use the 12mm (US 17) knitting needles and do the following:

  • Pick up and knit 12 (12, 14, 14, 16, 16) sts from the side front neck edge and top of the sleeve.
  • Then K across the 8 (10, 10, 12, 14, 14) sts from the stitch holder at the center front.
  • Then pick up and knit 12 (12, 14, 14, 16, 16) sts from the side front neck edge and top of the sleeve.
  • Finally K across the 20 (22, 22, 24, 26, 26) sts from the spare stitch holder at the back.

Please note the neck is now worked back and forth – not joined in the round.

Work in 1 x 1 ribbing (K1, P1) for 6 inches (or your desired length), ending with a WS row.

Cast off the rem sts in rib.

Step 5

Join rem back raglan seam and cont up the neck ribbing.

Step 6

Join side and sleeve seams using the mattress stitch.

Then you can weave in any leftover loose ends.

I also like to use a lint roller to clean the garment afterward in case of any fluff, pet hair, etc!

  1. This is the most beautiful sweater, it looks like a designer sweater you see in boutiques.the pattern and your directions are excellent, i have been looking for a design like this to knit for so long.
    If you are 5’2″, will the length be ok? I Realize the sweater is styled to drape as shown. Thank you for a great pattern and super simple directions.

    1. Hello Jen,
      I’m so happy you like the sweater.
      I think that the length will be fine, I am 5″3 and the model in the photos (my friend Nikoletta) is around 5″4 so it’s not super long.
      But when you knit the front or back piece, you can get to the point where you need to cast off for the armholes and see if the length is ok or not – holding it up against yourself and measuring.
      I hope that helps and happy knitting!

    1. Hello Colleen,
      I’m so happy you like the sweater!
      Yes, I think that Wool ease thick, and quick will also work for this sweater pattern.
      I haven’t tried it but the yarn weight is the same – so it will be ok.
      Both of those yarns, when knit up, are very thick and heavy, I made the long chunky cardigan in Lion Brand Wool ease thick and quick in graphite and it is very similar.
      I saw that another knitter had chosen a similar yarn called Grey River Chill by Sugar Bush – maybe you can check that out too.
      I hope that helps!

      1. Thankyou so much Louise. I’m also happy that the comment above mine mentioned length, as I am only 5’ tall….lol…I will take a look at the sugar bush yarn as well. 🙏

  2. Hello again😊
    I have a question,i have many skeins of #4 yarn, enough to make this sweater if i double strand,
    do you think this would work.i love the ease of this pattern and i think it wb withinh same thickness range on needle sizes called for.
    what do you think?
    Thank you.

    1. Hello Jen,
      You could try it but changing the yarn thickness will impact the overall finish of the sweater.
      Even knit with two strands together the medium 4 yarn will not have the same look as the super bulky.
      But you could definitely try it out to see how it goes?!
      That’s the exciting thing about the fiber arts, you can experiment and create something amazing by changing things up a bit!
      Let me know how it goes 🙂
      Louise

    1. Hello Natasha,
      You can use a longer cable size – around 100cm/40″ for the back and front and the same or a shorter size cable (24″) for the sleeves if you wish.
      Better to use a longer cable for the front and back so you can see the stitches and the size it is taking as it knits up.
      I hope that helps!
