Knitting a Cable-Down Cardigan with a Set-In Sleeve

A cabled cardigan with a tailored sleeve sits at the intersection of comfort and craftsmanship. The cable motifs travel vertically down the front bands and back, drawing the eye along the length of the garment, while the set-in sleeve creates a silhouette that sits neatly on the shoulder without the bulk of a drop shoulder or the structured feel of a raglan. For knitters who want a project that teaches new skills without overwhelming them, this combination rewards patience with a polished, ready-to-wear finish.

Australian makers often reach for a cardigan like this when the leaves start turning in late autumn. By the time the chill rolls in from the Brindabella Ranges, a hand-knit layer becomes part of the daily wardrobe. Working cables from the bottom up allows you to try on the body as you go, adjusting length and ease to suit your own shape, which matters when you are investing weeks of evenings at the local café knit-in into a single piece.

The set-in sleeve, sometimes called a tailored sleeve, is shaped with increases at the armhole and decreases at the cap, mimicking the seam of a ready-made jacket. It looks intimidating on paper but follows a simple rhythm once you internalise the stitch counts. Pairing that shaping with cables means paying attention to how the motif interacts with the neckline decreases and the armhole curve, which is where most of the learning happens.

In this guide, we walk through the construction logic, yarn choices suited to Australian weather, how to chart a cable repeat that survives the shoulder seam, and the finishing steps that make a hand-knit cardigan look store-bought. If you are new to lace projects and want to build the dexterity required for cable work, a lace stole with beads project makes a useful companion exercise between sessions.

Understanding the Construction

A cable-down cardigan is knit in pieces: back, two fronts, and two sleeves. The cables run vertically from the hem to the shoulder, which means the motifs are worked alongside the body shaping rather than being applied as a border. The set-in sleeve is knit separately, then seamed into the armhole with a tapered cap that mimics a tailored jacket.

The key relationship to understand is how the cable cross sits within the row. When you work a six-stitch cable every eighth row, those eight rows also need to accommodate increases for the waist or decreases for the armhole. Most patterns resolve this by placing the cable panel on a background of reverse stockinette, which makes the increases and decreases easier to hide while keeping the motif crisp.

For Australian knitters working through winter — perhaps during a quiet Sunday arvo at a Brunswick or Newtown wool shop — this construction offers a predictable rhythm. You knit the back first to confirm your gauge and tension, then the two fronts mirror each other, and finally the sleeves. The sleeve cap shaping is the last technical hurdle, and once you understand the increase rate, the whole garment falls into place.

Yarn and Gauge for a Drapey Hand-Knit

Choose a yarn that balances stitch definition with drape. A 100 per cent merino from the New England tablelands of New South Wales, or a wool-silk blend from a local mill, will hold the cable crosses without becoming stiff. Avoid super-bulk yarns; the cable will look heavy and the set-in sleeve will lose its tailored line. A 10-ply or DK-weight wool works well for a first attempt, though experienced knitters often prefer an 8-ply for a denser fabric.

Gauge matters more on this project than on a plain stockinette sweater. Cable work draws the fabric in slightly, so a swatch knit in the main pattern will give a more accurate measurement than a stockinette swatch. Aim for a swatch of at least 15 cm square, blocked and dried flat, before committing to the needle size. If your swatch measures too loose, drop a needle size; if too tight, go up.

Budget around $120 to $180 AUD for a women's medium in a quality Australian-spun wool. Local yarn shops in Melbourne's Fitzroy, Sydney's Surry Hills, or Adelaide's city fringe often stock mill-end cones that offer better value for large projects. Many offer a loyalty discount after a certain spend, which adds up over a winter of projects.

Charting and Knitting the Cable Pattern

Most cable charts are written over a multiple of stitches plus a selvedge allowance. A simple six-stitch cable that crosses left over right every eighth row translates to a chart that is six stitches wide and eight rows tall. The background stitches around the cable are usually reverse stockinette, which gives the cables a raised, sculptural look against a flat field.

When you place the cable on the back piece, count the centre stitches and work out from there. On the fronts, the cable sits closer to the centre front edge, often two or three stitches in from the button band. Keep a row counter on your needle or use the Notes app on your phone to track where the cable crosses fall in relation to the body increases.

Lining up the cables across the shoulder seam is one of the more satisfying moments of the project. Use stitch markers at the shoulder edges so you know exactly which cable cross on the back matches which on the front. If the cable pattern does not divide evenly across the shoulder width, add a plain stitch column to one side rather than fudging the motif — the eye notices a misaligned cable long before it notices a slightly wider seam.

Shaping the Set-In Sleeve and Body

The set-in sleeve is shaped with two phases: the underarm seam, where increases are worked at a steady rate up the length of the sleeve, and the sleeve cap, where decreases form the rounded top. The cap decreases typically happen every fourth or sixth row, depending on the depth of the armhole and the desired fit.

For the body, the front bands are knit as part of the front pieces to avoid a seamed edge that can pucker. Place a marker three stitches in from the edge to mark the button band line, and work the band stitches in a 1x1 rib that matches the neckband. If you are working buttonholes, plan the button placement first and count the rows up from the hem to position the first button at the underbust line.

Joining the sleeve to the body uses a set-in seaming technique, where the sleeve cap is eased into the armhole with a backstitch or mattress stitch. Pin the sleeve cap to the armhole at four points first — the underarm seam, the shoulder point, and two points in between — then work the seam from the outside in. This gives a smooth, rounded cap that sits flat on the shoulder without pulling.

Finishing, Blocking, and Long-Term Care

Blocking is the single most important step for a cable cardigan. Wet the finished pieces in cool water with a wool wash, roll in a towel to remove excess moisture, then pin out on a blocking mat to the measurements given in the pattern. Cables open up beautifully when blocked, and the sleeve cap takes on a smooth curve that makes the seaming nearly invisible.

Weave in ends with a tapestry needle, working the tails into the back of the stitch for at least five centimetres before trimming. For the cable panels, run the tail along the purl background rather than through the cable itself, which can distort the motif. Sew on buttons last, after the band has been blocked and dried.

To store your cardigan through the Australian summer, fold it with cedar blocks or lavender sachets to deter moths, and avoid hanging it on a wire hanger, which can distort the set-in sleeve. A cool, dry wardrobe shelf is ideal. Wash only at the end of the season, by hand in cool water, and dry flat away from direct sunlight to prevent the wool from yellowing.
