The Sigrid Boxy Jumper is a women's knitted sweater pattern designed by MillaMia, offering a relaxed, boxy silhouette with bold colourwork detailing.

The generous, contemporary shape and striking colour palette make this jumper a versatile wardrobe staple.

Garment Overview and Sizing

The Sigrid Boxy Jumper is worked to fit bust measurements ranging from 81 cm to 102 cm (32 in to 40 in), with actual garment bust measurements of 90 cm to 115 cm (35½ in to 45¼ in) across five sizes, providing a comfortable, relaxed ease. The length to shoulder ranges from 56 cm to 63 cm (22 in to 24¾ in) depending on size, and the sleeve length is a consistent 45 cm (17¾ in). The boxy fit is intentional and characteristic of the design, giving the finished jumper a modern, fashion-forward appearance.

Construction and Techniques

This pattern is constructed using a bottom-up, seamed, worked flat approach, meaning the individual pieces — body panels and sleeves — are knitted flat on straight needles and then sewn together during finishing. This traditional construction method gives knitters full control over tension and shaping, and is well suited to heavier yarn weights where working in the round can sometimes be more cumbersome.

The standout technique in this pattern is intarsia colourwork. Intarsia is a method of knitting with multiple colours within a single row, where each colour section uses its own separate length or bobbin of yarn rather than carrying yarn across the back of the work. This technique creates clean, distinct colour blocks without the added bulk of floats, which is especially important when working with a super chunky yarn weight. Knitters are advised to take their time with the intarsia sections and to be particularly careful when seaming the sleeves into the body, as neat finishing is key to achieving a sleek result rather than a bulky one.

Stitches Used

• Stocking stitch (stockinette stitch) – the primary stitch used throughout the body and sleeves, creating a smooth knitted fabric ideal for showcasing the intarsia colourwork
• Garter stitch – referenced within the pattern, typically used for borders or edging details
• Moss stitch (seed stitch) – also referenced, often used for textural contrast in trims or cuffs
• k2tog (knit two together) – a standard right-leaning decrease used for shaping
• m1 and m1p (make one) – increase stitches used to add width during shaping sections
