Lang PTO31-11 Jacket Cardigan Knitting Pattern

Lang PTO31-11 Jacket

What is Being Made

The Lang PTO31-11 is a knitted cardigan jacket worked in a classic bottom-up construction. This garment features a structured design with separate front and back panels that are seamed together, creating a tailored silhouette. The jacket is available in two sizes: S–M with a bust measurement of 44 inches (112 cm) and L–XL with a bust measurement of 50½ inches (128 cm). The finished length is 31½ inches (80 cm), making it a standard jacket length suitable for layering or wearing as an outer piece.

Techniques Used

This jacket is constructed using bottom-up seamed construction, meaning the pieces are knitted individually from the cast-on edge upward and then joined together using seaming techniques. The garment is worked flat on straight needles rather than in the round, which is the traditional approach for cardigan jackets. This method allows for precise shaping and the ability to work different stitch patterns across various sections of the garment.

The pattern incorporates neck shaping worked over multiple rows, with decreases strategically placed to create a comfortable neckline. Shoulder shaping is achieved through bind-off rows at regular intervals, creating a properly fitted shoulder line. Armhole shaping is marked and worked to accommodate sleeve cap ease. A neck extension is worked in ribbing after the main body is complete, adding a refined finishing detail to the neckline.

Stitches Used

• Ribbing (K1, P1): Used for the initial cast-on edge and cuffs, creating an elastic border that helps the garment maintain its shape. The rib pattern is also used for the neck extension, providing a classic finished edge.
• Horizontal Ridge Pattern: The primary stitch pattern used across the main body of the jacket, creating visual texture and interest while maintaining a relatively stable fabric.
• Knit and Purl Stitches: The foundation stitches that form both the ribbed sections and the horizontal ridge pattern.
• Decreases (K2tog and P2tog): Used for neck shaping to gradually reduce stitch counts in a way that blends seamlessly with the pattern.
• Bind-offs: Applied at the shoulders to secure stitches and create the finished shoulder line.

Materials and Tools

This jacket is designed to be knitted with Lang Yarns Cloud, an extra-fine merino wool blend that is mulesing-free and reinforced with nylon for durability. The yardage requirement is 700 grams (7 balls) for size S–M and 800 grams (8 balls) for size L–XL, both in the colorway green 1077.0004.

The pattern calls for ADDI knitting needles in two sizes: US 15 (10mm) needles for the ribbed sections and US 17 (12mm) needles for the main body. This needle size progression is typical in knitting patterns to create proper gauge and fabric density. The pattern is worked using two strands of yarn held together during the cast-on and ribbed sections, which creates a thicker, more elastic edge suitable for a fitted garment.

Pattern Construction Details

The jacket begins with casting on stitches for the right front panel: 30 stitches for size S–M or 34 stitches for size L–XL. After working a 2¼-inch (6 cm) ribbed cuff, the knitter transitions to the larger needles and begins the Horizontal Ridge Pattern while maintaining a 5-stitch rib at the beginning of rows. The front panels are worked until they measure 19¾ inches (50 cm) before neck shaping begins. Neck shaping involves decreasing stitches every 8th row for one size or alternating between 6th and 8th rows for the other size, with a total of 4 to 5 decrease rows. Armhole markers are placed when the front measures 22 inches (56 cm) for size S–M or 21¼ inches (54 cm) for size L–XL from the cast-on edge. After the armhole edge measures 8 to 8¾ inches (20–22 cm), shoulder shaping begins with bind-offs of 5 stitches on three right-side rows, followed by a final bind-off of either 4 or 6 stitches depending on size. The remaining 6 stitches are worked in rib pattern for the neck extension, which measures
