MillaMia Bia Jumper Knitting Pattern

MillaMia Bia Jumper: Knitted Striped Sweater

What is Being Made

The MillaMia Bia Jumper is an intermediate-level knitted sweater designed to fit chest sizes ranging from 76-82cm (30-32in) through 137-142cm (54-56in). This pullover-style jumper features a relaxing repetitive stripe pattern worked in four coordinating colors of MillaMia Naturally Soft Merino yarn. The finished garment offers a modern, versatile design suitable for various occasions, with finished chest measurements ranging from 91cm to 151cm (35¾in to 59½in) and a consistent sleeve length of 45cm (17¾in).

Techniques Used

The Bia Jumper is worked flat on straight needles, meaning the front and back pieces are knitted separately and then seamed together. The primary construction method involves working in rows rather than in the round, allowing for straightforward pattern repeats and color changes. The stripe pattern forms the visual focus of the design, with colors introduced systematically throughout the knitting process. This technique creates a calm, meditative knitting experience due to the repetitive nature of the color sequences.

Stitches Used

The Bia Jumper employs two primary stitch patterns. The main fabric is worked in stocking stitch (stockinette stitch in US terminology), which creates a smooth, classic knit fabric with characteristic V-shaped columns on the right side. Ribbed sections use moss stitch (also known as seed stitch), which produces a textured, bumpy fabric ideal for cuffs and waistbands that provide elasticity and structure. The combination of these stitches creates visual and tactile interest while maintaining the garment's wearability.

Materials and Yarn Specifications

This pattern requires MillaMia Naturally Soft Merino yarn in 50g/1¾oz balls. The yarn quantities vary by size, with the primary color (Rain 165, designated as color A) requiring between 5-7 balls depending on the size selected. Secondary colors include Ice 125 (B), Forget Me Not 120 (C), and Tempest 167 (D), with quantities ranging from 2-3 balls for colors B and D, and 4-5 balls for color C. The pattern is photographed in cool, sophisticated shades but offers alternative colourways: Colourway 2 features Snow, Lilac Blossom, Fuchsia, Haze Grey, Petal, and Tempest; Colourway 3 includes Blossom, Haze Grey, Ice, and Blue Berry.

Needles and Tools Required

• Pair of 3mm (US 2) knitting needles for ribbed sections
• Pair of 3.25mm (US 3) knitting needles for main fabric
• Circular 3mm (US 2) knitting needle for larger sizes
• Circular 3.25mm (US 3) knitting needle for larger sizes

Tension and Gauge Information

Achieving correct tension is essential for proper fit. The pattern specifies 25 stitches and 34 rows to 10cm/4in square over stocking stitch using 3.25mm (US 3) needles. For moss stitch sections, the gauge is 24 stitches and 41 rows to 10cm/4in square using the same needle size. These tension measurements should be checked on a swatch before beginning the project to ensure the finished garment matches the intended dimensions.

Design Features and Construction Details

The Bia Jumper accommodates seven different sizes with graduated measurements, making it suitable for a wide range of body types. Length adjustments are available, with the back neck length ranging from 58cm (22¾in) for the smallest size to 64cm (25¼in) for the largest size. The seamed construction method allows for straightforward assembly once all pieces are completed, with the stripe pattern creating visual continuity across the body and sleeves. The repetitive nature of the stripe sequence makes this an ideal project for knitters seeking a meditative, rhythmic knitting experience while still developing intermediate-level skills.
