Sirdar Jacket Coat Knitting Pattern

Sirdar Alpine Jacket

What is Being Made

The Sirdar Alpine Jacket is a seamed, button-front knit jacket designed in a super chunky yarn. This garment is constructed using the bottom-up method and worked flat on straight needles, making it an accessible project for knitters comfortable with basic shaping and seaming techniques. The jacket features a classic tailored silhouette with set-in sleeves and is available in six sizes ranging from 81/86 cm (32/34") chest to 132/137 cm (52/54") chest.

Techniques Used

This jacket is worked flat on straight needles rather than in the round, meaning each piece is knitted separately and then seamed together. The bottom-up construction method is employed, where the body and sleeves are knitted from the cast-on edge upward to the shoulders. The garment uses seaming to join the front panels to the back, attach the sleeves, and close side seams. Shaping is achieved through strategic cast-offs at the beginning of rows to create armholes and shoulder decreases, a fundamental technique for tailored garment construction. The pattern includes button bands and requires careful measurement of pieces while hanging, as noted in the instructions due to the heavy nature of the super chunky yarn.

Stitches Used

The primary stitch throughout the Alpine Jacket is stocking stitch (also known as stockinette stitch), which creates a smooth, classic fabric with a recognizable V-pattern on the right side. Garter stitch is used for the button bands and edges, providing a textured, reversible finish that adds structure and prevents curling. The combination of these two fundamental stitches makes this pattern suitable for knitters with intermediate skills who understand basic increases, decreases, and shaping principles.

Materials and Specifications

The Alpine Jacket is designed to be knitted in Sirdar Alpine Super Chunky yarn (50g balls). The pattern requires two complementary shades: shade 411 (Yarn A) and shade 413 (Yarn B). Yardage requirements vary by size, with smaller sizes requiring 8 balls of Yarn A and 6 balls of Yarn B, increasing to 13 balls of Yarn A and 9 balls of Yarn B for the largest size (XXXL). The project requires two pairs of knitting needles: 10mm (UK000/USA15) needles for the main fabric and 8mm (UK0/USA11) needles for the cast-on and button bands, allowing for proper tension control. A single Sirdar Elegant Button (Code B5-611-0305) completes the closure. The recommended tension is 8.5 stitches and 12 rows over 10 cm (4") in stocking stitch on 10mm needles.
