"Kasper Jacket" - Jacket Knitting Pattern For Girls in MillaMia Naturally Soft Merino

Kasper Jacket – Girls' Knitting Pattern by MillaMia

The Kasper Jacket is a stylish, contemporary children's jacket knitting pattern from MillaMia, designed to be knitted in MillaMia Naturally Soft Merino yarn. Described as cool, contemporary, and wonderfully warm, this jacket is presented as a versatile, unisex-friendly design that works equally well for boys and girls. A clever construction detail makes this possible: decorative buttons sit on the outside for visual appeal, while internal poppers (snap fasteners) handle the actual fastening — and can be positioned to create either a boy-style or girl-style opening. The result is a garment that is as practical as it is good-looking.

Sizes and Fit

The Kasper Jacket is sized to fit children aged 2–3, 3–4, 4–5, 5–6, and 6–7 years, making it a pattern with excellent longevity across the early childhood years. Actual garment measurements are as follows:

• Chest: 58, 62, 68, 72, and 76 cm (approximately 23 to 30 inches)
• Length to shoulder: 28, 32, 36, 40, and 44 cm (approximately 11 to 17½ inches)
• Sleeve length: 24, 27, 30, 33, and 36 cm (approximately 9½ to 14¼ inches)

These generous size increments mean the jacket can be knitted to grow with a child, and the range of sizes gives knitters the flexibility to choose a slightly larger size for extra wear time.

Construction and Techniques

The Kasper Jacket is constructed using a bottom-up, worked flat, and seamed method. This is a traditional approach to garment knitting that many knitters find reassuring and straightforward, particularly those who are building their skills. Working flat means each piece — typically the back, two fronts, and sleeves — is knitted back and forth on straight or circular needles rather than in the round. The pieces are then joined together using seaming techniques, which give the finished jacket a neat, structured finish with clean edges.

Knitting bottom-up is the conventional direction for most classic garment patterns: you begin at the lower hem and work upward toward the shoulders. This approach makes it easy to adjust length before committing to the armhole shaping, which is a useful feature when knitting for children whose measurements can vary.

Collar Construction

The pattern includes a collar, and the instructions specifically note that knitters should keep in mind the distinction between left and right as worn — meaning the left side as the wearer would experience it, not as the knitter sees the fabric. This is a standard but important reminder when working on front bands and collar sections of a jacket, where the two sides mirror each other and confusion can lead to mistakes.

Skill Level

The Kasper Jacket is rated as Improving in skill level, which in MillaMia's grading system sits just above true beginner. This makes it an excellent choice for knitters who have mastered the very basics — casting on, knit and purl stitches, and binding off — and are ready to tackle a more complete garment with shaping, button bands, and collar work. The seamed construction is also a valuable skill to develop, as it introduces knitters to mattress stitch and other finishing techniques that are fundamental to producing professional-looking knitwear.

Materials

The pattern calls for MillaMia Naturally Soft Merino yarn, a sport weight yarn sold in 50g / 1¾oz balls. The quantity required ranges from 5 to 9 balls depending on the size being knitted (5 balls for the smallest size, up to 9 balls for the largest). MillaMia Naturally Soft Merino is a machine-washable merino wool yarn, making it a highly practical choice for children's garments — it offers the softness and warmth of natural merino fibre without the delicacy that can make hand-wash-only garments impractical for everyday family life.

Why Merino Wool for Children's Knitwear?

Merino wool is widely regarded as one of the finest natural fibres available for next-to-skin wear. Its fine fibre diameter means it is far less likely to cause the itching or irritation associated with coarser w
