Structured Seams

I love a good, complicated knit. Throw me an all-over cabled sweater, colorwork knit flat, lots of shaping or unusual construction. But sometimes it's just nice to sit down and knit the darn sweater. I can't tell you this sweater is entirely without shaping – it has to fit after all. And it's not without a bit of detail work, either. But it's the fun kind – at least to me!

This squishy garter sweater begins at the top with the saddles and works its way downward. Slipped I-cord edges and I-cord bind-offs form the look of exposed seams in this oversized sweater. Short-row shaping is thrown in at the shoulders for good measure, but there's nothing super fussy about this garment. I made my samples in two different sizes, resulting in 7.5 and 11.5 inches of ease respectively, and I love them both! These are destined to become wardrobe staples that I'll be reaching for time and again over the years.

Yarn Characteristics
spacer The caramel sample shown uses a fingering weight superwash merino/nylon blend. Most wool or wool blends will work well for this project. Avoid using plant fibers for this project as it would end up being very heavy due to the garter stitch in this project. The aubergine sample uses a plied acrylic yarn.

PATTERN NOTES

[Knitty's list of standard abbreviations and techniques can be found here.]

Construction method: Saddles are knit first from the neck outward. Stitches are picked up from one side of the saddles and the back is knit downward, flat. Shoulders are shaped using short-rows. Stitches are then picked up from the other side of the saddles and the front is knit downward, flat. Shoulders are shaped using short-rows. Sleeve stitches are a combination of being picked up from the sides of the front and back, and also live stitches from the ends of the saddles. They are knit downward, flat.

It's important to match row gauge because specific numbers of stitches are picked up around armholes for sleeves. That being said, try not to sweat it too much as garter stitch is stretchy and forgiving.

Techniques:

  • 2-Stitch I-Cord Bind-Off
    Cast on 2 sts using the knitted method. *K1, k2tog tbl, sl these 2 sts back to left needle; rep from * until all sts have been bound off, bind off rem 2 sts.
  • sewn tubular bind off single needle method (photo tutorial)
    OR holding 2 smaller needles parallel (your working needle plus another needle), sl knit sts to the front needle and sl purl sts to the back needle, and bind off using the standard stockinette stitch graft.

K1, p1 Ribbing (odd number of sts)
Rnd 1: * K1, p1; rep from * to end.
Rep Rnd 1 for patt.

Kfpb: knit into the front loop of the next st, then purl in the back loop of the same st. 1 st increased.

Amy is currently the senior creative manager for Premier Yarns. She also does freelance design work, technical editing, crochet chart making, and many other assorted yarny things. When she's not busy with fiber, she's probably playing tennis, dog snuggling, or sitting in the corner being antisocial.
