Diamond Texture Jumper

Diamond Texture Jumper by Sian Brown

What is Being Made

The Diamond Texture Jumper is a knitted pullover sweater designed by independent knitwear designer Sian Brown. This garment features an all-over diamond texture pattern created through a combination of knit and purl stitches. The jumper is available in three sizes—Small, Medium, and Large—with finished bust measurements of 110 cm (43½ in), 130 cm (51½ in), and 150 cm (59 in) respectively. The length ranges from 65 to 69 cm (25½ to 27 in) depending on size, with consistent sleeve length of 45 cm (17¾ in) across all sizes.

Craft and Techniques

This is a knitting project classified as beginner level, making it an accessible choice for those new to garment construction. The sweater is worked using the fundamental knitting technique of combining knit and purl stitches to create textured surface patterns. The diamond texture emerges from the strategic placement of these basic stitches across a 20-stitch repeat pattern panel, which is worked over multiple rows to build the complete three-dimensional diamond effect. The pattern demonstrates how simple stitch manipulation—without requiring advanced techniques like cables or colorwork—can produce visually striking texture and depth in a finished garment.

Stitches Used

The Diamond Texture Jumper relies on two fundamental stitches:

• Knit stitch (k): The primary stitch used to create the raised portions of the diamond pattern
• Purl stitch (p): Used to create recessed areas that define the diamond shapes and add visual contrast

The pattern panel is worked over 20 stitches and repeats across multiple rows. The reverse stockinette sections (created by purling on right-side rows) recede visually, while the knit stitches advance, producing the dimensional diamond effect. All wrong-side rows follow a consistent rule: purl the purl stitches and knit the knit stitches as they appear, which maintains pattern continuity throughout the garment.

Materials and Needles

The Diamond Texture Jumper is designed to be worked in Cascade 220, a 100% wool yarn that knits to aran weight. Yardage requirements vary by size: 7 hanks (1,400 meters) for Small, 8 hanks (1,600 meters) for Medium, and 9 hanks (1,800 meters) for Large. The pattern calls for the Magenta colorway (shade 7803), though the design would work equally well in other Cascade 220 colors.

Knitting needles required are a pair each of 4.5mm and 5mm needles. The smaller needles are typically used for ribbed edgings and cuffs, while the larger 5mm needles are used for the main body and pattern sections. The pattern is calibrated to a tension of 19 stitches and 29 rows over 10 x 10 cm (4 x 4 in) when worked in the diamond pattern using 5mm needles, which is standard for aran-weight yarn and ensures proper garment fit and drape.
