Knitted sweater

Added: 12.11.2025 в 21:31 Views: 4663

The sweater is knitted from the top down and features a dropped shoulder with extended sleeves for a feminine and cozy look.
The work begins by shaping the flat back piece, while increasing the shoulder seams, then stitches are picked up from the right and left shoulders for the front portion of the back.
Then the front and back pieces are joined together and worked in the round for the body. Cast on stitches for the sleeves and work the circular seams, and then pick up stitches for the collar with a double-fold collar.

The sweater is worked on 5 mm needles (US 8) from a single strand of merino and a strand of silk mohair or from DK / Worsted yarn.
The collar, hem, and cuffs are worked in twisted rib on 3 mm needles (US 2.25).

1×2 RIBBED SEAM

Choose a size that is 15–20 cm / 6–8" larger than your bust circumference to create a relaxed and slightly oversized look, which will also allow the fabric to drape nicely.
Tip: if you are between sizes, choose the larger one.

Gauge in size S: Bust ≈ 87 cm / 34.25".

GAUGE:
17 sts × 24 rows = 10 cm in 1×2 rib on 5 mm needles (US 8) after blocking.
19 sts × 25 rows = 10 cm before blocking.
18 sts × 30 rows = 10 cm on 3 mm needles (US 2.5) in 1×1 twisted rib after blocking.

Do not cut the yarn yet — next comes the joining of the left and right front pieces.

Joining the left and right parts

Then join the left and right front pieces,
by picking up new stitches to form the center section of the neckline.

Continue work as follows:

Row 1 (RS):
K2, p2, k1 to the last 4 stitches of the right front piece, k2, p1,
CO 18 (21, 27, 27, 27) (27, 30, 30, 30) sts by Backwards Loop Cast-On,
slip the stitches of the left front piece onto the working needle and join:
p1, k1, p2 to the last 2 stitches, k2.

→ Now on needles 170 (190, 210, 230, 250) (264, 294, 322, 336) sts.

Row 1:

K to the side marker for the body, SM,
K to the BOR marker BOR.

💡 Note: the BOR marker is located in the middle of the side of the body to ensure that the cable pattern (Scheme B) is aligned correctly.
In this row, the stitches picked up in the previous joining round have not yet been worked.

SECTION 5

Start working from Scheme B in the chosen size,
starting at the BOR
and knitting all body stitches,

for each sleeve on circular needles 5 mm (US 8) 40–60 cm long
(or longer if you are using the «magic loop» technique),
starting from the underarm center.

and knit 22 rounds in pattern k1 tbl, p1 (twisted rib 1×1),
or until the cuff length reaches 7.5 cm / 3".

Bind off stitches using the Italian method in the round.

NECKLINE

To shape the neckline, pick up stitches along the neckline edge
and knit 1×1 rib on circular needles 3 mm (US 2.5).
Start the pickup at one of the shoulder seams — between the front and back yoke.
Place a marker to mark the start of the round.

Cast on and knit 96 (100, 100, 104, 104) (104, 104, 108, 108) stitches

Collar assembly:

Sew the edges of the collar using a standard method.
Then fold the collar in half — toward the wrong side.
Carefully attach the inner edge by hand along the base,
ensuring the neckline does not become too narrow.
