Inspired By The Outlander Knits

If you have been watching the Outlander TV series, through all of the seasons, Claire and the other characters have been seen wearing an amazing selection of knits.

From Claire and Brianna’s cowls, wraps, shawls, and mittens to Roger and Brianna’s sweaters in seasons three and four.

You can see them wearing carefully curated pieces in mainly neutral tones, like brown, beige, navy, and grey.

This pattern is part of my Outlander collection, you can see the other Outlander patterns here. – Outlander Patterns {Beginner + Intermediate}

How To Knit The Half Fisherman’s Rib Stitch

This stitch pattern is similar to the 1 x 1 or 2 x 2  rib stitch but has a more defined texture.

This is a simple stitch to work, as you knit a one-row repeat stitch with a setup row.

This stitch definitely gives the sweater that extra warm and cozy look!

It is knit like this:

Cast on stitches in a multiple of 2 + 1.

  1. Row 1: (RS) Knit to the end of the row.
  2. Row 2: (WS) K1, *P1, K1B, rep from * to last 2 sts, P1, K1.
  3. Rep Rows 1 and 2 for the pattern.

  1. What is the reason for knitting the right side, then ribbing, then knitting a row, then ribbing instead of just ribbing both sides? Is it an aesthetic thing? I’m not sure I’ve ever seen it done that way before and want to make sure I’m not just misreading.

    I just repeat these two rows correct?
    Row 1: (RS) Knit
    Row 2: K1, *P1, K1B, rep from * to last 2 sts, P1, K1.

    1. Hello Claire, this is knit in half Fisherman’s rib. The ribbing stands out a lot more than if you just knit say 2 x 2 ribbing. You repeat the rows given in the pattern and you will see the ribbing start to take effect. Happy Knitting! 🙂

  2. Hi Louise
    I’m not sure what this means: Cast on stitches in a multiple of 2 + 1.
    Can you please explain.
    Thank you

    1. Hello Britte,
      For the half fisherman rib pattern, this works out when the number of stitches you cast on is in a multiple of 2+1.
      This means that extra stitches are needed to keep everything balanced (symmetrical) but the extra stitches are not part of the actual stitch pattern.
      When you see multiples like this, the extra stitches are done at the beginning and/or the end of the row and lots of times they help form the selvedge (the edge).
      The actual number of stitches you need to cast on for each piece of the garment has been listed in the pattern for the different sizes.
      I hope that helps!

  3. hi!! I was wondering how you advise to increase on the half fisherman’s rib while maintaining the pattern. having some difficulties! thank you!

    1. Hello Kendall,
      For the increases – I would suggest using KFB – knit into the front and back of the stitch.
      Then keep the stitch pattern correct as you work and increase further.
      I hope that helps!

      1. Hi! It seems the increases for sleeves are done on the knit row 1. Once I have increased the 2 stitches, not sure how to adjust for Row 2?

        1. Hello Meg,
          The increases for the sleeves are done on the 3rd row and then every following 4th row until you have 43, (45, 45, 47, 51, 51) sts.
          You can KFB into the sts – this will work for the increases well.
          So inc by using KFB on the 1st and last st of the 3rd row, turn and then KFB into the first and last st of the next (4th row).
          I hope that helps!

      2. Disappointed that you list the yarn weight as 05 Bulky, but the yarn you used, recommended, (and is impossible to find), is 06 super bulky weight. So here I sit with size 5 bulky yarn , ready to go… but I have to buy new yarn….Do you have a pattern that uses 05 weight yarn ;-(

        1. Hello Ellen,
          The yarn I used is between bulky and super bulky, it can be used with 8mm (US 11) or 9mm (US 13) needles.
          The sweater uses 6.5mm (US 10.5) knitting needles and 8mm (US 11) knitting needles so you will be able to use your bulky yarn for this pattern.
          The Drops Eskimo which has now been renamed as Drops Snow can be found at Wool Warehouse – or if you check the Garn Studio website they may have a list of stockists you can check out.
          I also have a cardigan pattern that uses bulky yarn here – https://www.handylittleme.com/cardigan-knitting-pattern/
          I hope that helps!
