Sirdar 8122 – Knitted Jacket in Sirdar Cotton DK

Pattern 8122 from Sirdar is a downloadable PDF knitting pattern for a classic knitted jacket worked in Sirdar Cotton DK yarn. Designed at an intermediate skill level, this versatile pattern includes an impressively wide size range, making it accessible to a broad range of knitters. The finished jacket is a wardrobe-friendly, structured piece that works beautifully as a layering garment across spring, summer, and early autumn thanks to the breathable cotton fibre content of the recommended yarn.

Sizes and Finished Measurements

The pattern covers six sizes, designed to fit bust measurements from 81/86 cm (32/34 in) up to 132/137 cm (52/54 in), with the pattern explicitly noted as including larger sizes. The actual finished garment measurements range from 91 cm (36 in) to 142 cm (56 in) across the chest, providing a comfortable, slightly eased fit. Full length, measured from the back of the neck, ranges from 60 cm (23¾ in) to 73 cm (28¾ in) depending on size, while the sleeve length is a consistent 31–32 cm (12–12½ in) across all sizes — a neat three-quarter or shorter sleeve length suited to warmer weather wear.

What Is Being Made

The project is a knitted jacket — a structured, shaped garment with set-in or tailored sleeves. As a jacket rather than a simple cardigan, it is designed to have a more defined silhouette, making it a slightly more involved knit that rewards the intermediate knitter with a polished, wearable result. The inclusion of multiple size options up to a 52/54 in bust makes this an inclusive and practical pattern choice.

Techniques Used

• Shaping: As an intermediate-level jacket pattern, knitters will work increases and decreases to shape the body panels, armholes, and sleeves — essential skills for achieving a well-fitted garment.
• Seaming and construction: The jacket is knitted in separate pieces (front panels, back, and sleeves) which are then sewn together, requiring neat mattress stitch or backstitch seaming for a professional finish.
• Tension/gauge management: Working to the specified tension is particularly important in a fitted jacket to ensure the finished measurements match the intended size.
• Ribbing or edging: Necklines, cuffs, and front bands on jackets of this type typically incorporate ribbed or moss stitch borders, worked on finer needles to create neat, firm edges.

Stitches Used

• Knit and purl stitches form the foundation of the fabric throughout the jacket body and sleeves.
• Rib stitch (typically k1, p1 or k2, p2) is characteristic of jacket edgings, cuffs, and front bands in patterns of this style, providing elasticity and structure at the borders.
• Stocking stitch (stockinette) is the most likely primary fabric stitch for the main body sections, creating a smooth, classic surface that showcases the cotton yarn beautifully.
