Lang PTO31-10 Jacket Coat Knitting Pattern

Lang PTO31-10 Jacket

What Is Being Made

The Lang PTO31-10 is a knitted jacket worked in a bottom-up construction method. This garment features a classic seamed jacket design with front and back panels worked flat on straight needles. The finished jacket offers generous sizing with bust measurements of 44 inches (112 cm) for size S–M and 50½ inches (128 cm) for size L–XL, with an overall length of 31½ inches (80 cm). The design includes structured shoulder shaping, armhole placement, and a neck extension detail that adds a refined finishing touch to the neckline.

Techniques Used

This jacket is constructed using the bottom-up seamed method, meaning the knitter begins at the lower edge of the garment and works upward, then seams the pieces together. The pattern is worked flat on straight needles rather than in the round, allowing for easy shaping and pattern work across front and back panels. Key shaping techniques include:

• Decreasing for neck shaping: Strategically placed decreases worked every 8th row or alternating 6th and 8th rows to create a fitted neckline
• Armhole marking: Markers placed to establish armhole positions at specific measurements from the cast-on edge
• Shoulder shaping: Bind-off rows at the beginning of right-side rows to create structured shoulder seams
• Neck extension: A ribbed extension worked over remaining stitches to create a finished neckline detail

Stitches Used

The Lang PTO31-10 jacket employs a combination of fundamental and textured stitches to create visual interest and structure:

• Ribbing (K1, P1): Used for the initial cuff sections and the neck extension, providing elasticity and a finished appearance
• Horizontal Ridge Pattern: The primary stitch pattern used across the main body of the jacket, creating horizontal texture lines that add depth and visual dimension to the garment
• Knit and purl stitches: Basic stitches combined to form the foundation of both the ribbing and ridge patterns
• Decreases (K2tog and P2tog): Used for shaping the neckline while maintaining pattern continuity
• Bind-offs: Applied at shoulders to secure stitches and create finished edges

Materials

The Lang PTO31-10 jacket is designed to be worked in LANGYARNS CLOUD, an extra-fine merino wool blend that is mulesing-free and reinforced with nylon for durability. The yarn composition provides softness, breathability, and resilience suitable for a wearable jacket. Yardage requirements are 700 grams (7 balls) for size S–M and 800 grams (8 balls) for size L–XL in the green colorway 1077.0004.

The pattern specifies ADDI knitting needles in two sizes: US 15 (10mm) for the ribbed cuff sections and US 17 (12mm) for the main body and pattern work. The two-needle size approach allows for proper gauge and texture development, with the larger needles creating the characteristic drape and texture of the Horizontal Ridge Pattern while the smaller needles provide a tighter, more elastic cuff.

Pattern Structure and Construction Details

The right front panel is cast on with 30 stitches for size S–M or 34 stitches for size L–XL using two strands of yarn and the smaller needles. After establishing a 2¼-inch (6 cm) ribbed cuff, the knitter switches to the larger needles and begins the Horizontal Ridge Pattern with 5 stitches of rib maintained at the beginning of each row for a finished front edge. The front piece is worked until it measures 19¾ inches (50 cm), at which point neck shaping begins through strategic decreases. Simultaneously, armhole markers are placed when the front reaches 22 inches (56 cm) for size S–M or 21¼ inches (54 cm) for size L–XL. Shoulder shaping occurs 8 to 8¾ inches (20–22 cm) above the armhole edge, with bind-offs of 5 stitches on three right-side rows followed by a final bind-off of 4 stitches for size S–M or 6 stitches for size L–XL.
