Olle Jumper and Hat Knitting Pattern by MillaMia – Detailed Pattern Summary

The Olle Jumper and Hat is a charming beginner-to-improving level knitting pattern from MillaMia, designed for babies and toddlers aged 3 months through 24 months. The collection includes two separate but coordinating projects: a striped raglan jumper (sweater) and a matching striped hat, both worked in MillaMia Naturally Soft Merino sport weight yarn. The pattern is available as a downloadable PDF and is an excellent choice for knitters who are building their skills beyond the very basics while still working with accessible, well-structured instructions.

The Olle Jumper

What Is Being Made

The Olle Jumper is a striped raglan-sleeve baby and toddler jumper worked in a classic two-colour stripe pattern with small accent colours carried over from the hat. The raglan shaping is highlighted as a decorative feature, making the most of the stripe sequence across both the body and the sleeves. The jumper includes a button band, making it easy to dress and undress young children. It is sized to fit ages 3–6, 6–9, 9–12, 12–18, and 18–24 months, with actual chest measurements ranging from 51 cm to 64 cm (20 in to 25 in).

Techniques Used

• Bottom-up construction – the jumper is begun at the lower edges and worked upward toward the shoulders, a logical and beginner-friendly approach.
• Seamed construction – pieces are worked flat and then sewn together, making it easy to manage tension and work in sections.
• Worked flat – all pieces are knitted back and forth in rows rather than in the round.
• Stripes – a two-colour stripe sequence using the main colour and a contrast colour forms the body and sleeve fabric, with small amounts of accent colours adding detail.
• Buttonhole technique – the button band incorporates 4 buttonholes to accommodate buttons approximately 15mm in diameter.
• Raglan sleeve shaping – the raglan decrease lines are treated as a design feature, creating a neat and visually interesting yoke area.

Stitches Used

• Stocking stitch (stockinette stitch) – the primary stitch used for the body and sleeves, creating a smooth knitted fabric ideal for showcasing stripes.
• Garter stitch – likely used for borders or edgings, as is typical in MillaMia baby patterns at this skill level.
• Decreases and increases – used for raglan shaping and sleeve tapering.
• Buttonhole stitches – worked into the button band to create neat, functional openings.
