Rowan Lattice Jumper Knitting Pattern

Rowan Lattice Knitted Sweater by Martin Storey

What Is Being Made

The Rowan Lattice is a knitted sweater designed by Martin Storey, available in five sizes to fit bust measurements from 81-86 cm (32-34 inches) up to 122-127 cm (48-50 inches). This is a classic pullover-style jumper with a structured silhouette featuring shaped shoulders and a finished waist measurement ranging from 69 cm (27 inches) to 109 cm (43 inches) depending on size selection.

Construction Method

This sweater is constructed using a bottom-up, seamed, and worked-flat approach. The garment pieces are knitted individually in flat rows rather than in the round, then carefully seamed together. This traditional construction method allows for precise shaping at the shoulders, waist, and neckline, with distinct front and back panels that are worked separately and joined.

Knitting Techniques

• Stocking stitch forms the primary fabric, creating a smooth, classic knit surface
• Ribbed edging is used for structure and elasticity, worked in a knit-purl pattern (P1, K2 repeat) at the cast-on edge
• Shoulder shaping is achieved through strategic cast-offs worked at the beginning of rows, creating a stepped decrease that forms the armhole and shoulder seams
• Waist shaping involves single-stitch decreases worked at each end of rows to create a fitted silhouette
• Neckline shaping includes cast-offs and decreases to create a finished neck opening with proper depth and width
• Front opening division creates a structured front panel separation

Stitches Used

• Knit stitch (K) – the fundamental stitch creating the smooth face of the fabric
• Purl stitch (P) – used in ribbed edging patterns for texture and elasticity
• Cast-on and cast-off techniques – for securing stitches at edges and shaping shoulders
• Decreases – single-stitch reductions worked at garment edges for fitted shaping

Materials and Gauge

This pattern calls for Rowan Softyak DK yarn, a soft, durable yarn weight suitable for structured garments. The project requires 10-15 x 50-gram balls depending on size selection (photographed in the colorway Taupe 245). Knitting needles required are 3¼mm (US 3) for ribbed edging and 4mm (US 6) for the main fabric. The working tension is 22 stitches and 30 rows to 10 centimeters measured over stocking stitch using the 4mm needles, which is essential for achieving the correct finished garment measurements.

Pattern Details

The back panel begins with a cast-on of 223-287 stitches depending on size, with the initial rows worked in knit-purl ribbing for a finished edge. The front features a divided opening created by casting off stitches at a marked point. Both front and back pieces are worked straight for approximately 10-11.5 centimeters before shoulder shaping begins. Shoulder decreases are worked over multiple rows, with cast-offs of 4 stitches and 3 stitches creating a graduated slope. The neckline is shaped with additional decreases at the neck edge while simultaneously working shoulder cast-offs, creating a professional finish.
