A cable-pattern sweater that looks ready-made but is entirely hand-knitted. Sized for 9–10 year old boys, with detailed instructions for every section from rib border to invisible seaming.

Cable sweaters are the gold standard of hand knitting — nothing says "handmade with skill" quite like a well-executed cable pullover. This pattern creates a ready-made style sweater for a 9–10 year old boy, complete with side cables, a bold centre cable panel, and clean finishing.

Materials

• Thick yarn — Red Heart (imported) or similar weight like Ganga Pound of Happiness, Olivia, or Desire
• Size 6 knitting needles
• A cable needle
• Tapestry needle for seaming

Step 1: Ribbed Border

Cast on 70 stitches. Work a 2×2 rib border (knit 2, purl 2) for 10 rows. Then increase 12 stitches evenly across the row, bringing the total to 82 stitches.

Step 2: Cable Pattern Setup

Arrange the stitches into the cable layout:

• Side cables: 8 stitches each (left and right)
• Centre cable: 20 stitches
• Gap stitches: 2 purl stitches between each cable section
• The remaining stitches form the background fabric

The cable pattern repeats every 8 rows. Two small side cable crossings (16 rows) align with one large centre cable crossing (16 rows), keeping everything in sync.

Step 3: Knit the Body

Work 9 pattern blocks (72 rows total). At this point, the piece should measure approximately 13 inches long and 14 inches wide (with stretch).

Step 4: Neck and Shoulder Shaping

This is a round-neck style with no separate collar or button band. Decrease 1 stitch at both ends on every right-side row while maintaining the cable pattern. For the front, decrease stitches 42 times on both sides, with extra decreases in the centre for the neckline curve.

Back Panel

The back uses a simpler textured pattern for comfort against the skin. Start with 79 stitches and decrease similarly until 35 stitches remain.

Step 5: Sleeves

• Cast on 30 stitches, increase to 35
• Increase 1 stitch every 7th row for gradual widening
• Continue until the sleeve measures approximately 13 inches
• Shape the sleeve cap with decreases matching the body armhole

Step 6: Neck Finishing

Cast on 5 extra stitches for the neck overlap. Switch to smaller needles and work a 2×2 rib while decreasing for fit. Attach sleeves and back while knitting the neckband. Create a single buttonhole for the neck closure.

Step 7: Assembly

• Bind off using tubular bind-off for a clean, elastic edge
• Join shoulders with invisible seaming
• Set in sleeves and seam the sides
• Weave in all ends neatly

The finished sweater is stretchable, stylish, and has the look of a store-bought garment — but with the quality and character that only hand knitting can achieve.
