Freddie Jumper - Knitting Pattern for Boys in Willow & Lark Poetry

Freddie Jumper – Knitting Pattern for Boys by Willow & Lark

The Freddie Jumper is a charming children's Fair Isle jumper designed by Willow & Lark and knitted in their own Poetry DK yarn. The pattern is available as a downloadable PDF and is rated intermediate in difficulty, making it a rewarding project for knitters who are comfortable working with multiple colours and reading simple colourwork charts. The finished garment is a classic, colourful pullover sweater with stranded colourwork panels, sized to fit boys aged 2–3 up to 8–9 years.

What Is Being Made

The Freddie Jumper is a long-sleeved children's pullover sweater featuring traditional Fair Isle-style stranded colourwork. It is a seamed construction, meaning the front, back, and sleeves are each knitted as separate flat pieces and then sewn together to create the finished garment. This classic construction method gives the jumper excellent structure and durability — ideal for everyday children's wear.

The pattern is offered in four sizes, designed to fit chest measurements from 56 cm (22 in) up to 71 cm (28 in), corresponding to ages 2–3, 4–5, 6–7, and 8–9 years. Finished chest measurements range from 63 cm (24¾ in) to 79 cm (31 in), with a little positive ease built in for comfortable, active wear. Sleeve seam lengths range from 23 cm (9 in) to 35 cm (13¾ in) depending on the size.

Techniques Used

• Worked flat (back and forth on straight needles): All pieces — the front, back, and sleeves — are knitted flat in rows rather than in the round. This is a traditional approach well suited to seamed garment construction.
• Stranded colourwork (Fair Isle): The jumper features stranded knitting, a technique in which two or more yarn colours are used across a row, with the unused colour carried loosely across the back of the fabric. This creates the characteristic colourwork motifs associated with Fair Isle and Nordic knitwear. Managing yarn tension evenly across the floats is key to a neat, professional result.
• Seamed construction: Once all pieces are complete, they are joined using seaming techniques such as mattress stitch or backstitch. Seamed garments are known for their stability and are often preferred for children's clothing as the seams add reinforcement at stress points.

Stitches Used

• Stocking stitch (stockinette stitch): The main fabric of the jumper is worked in stocking stitch — knit on the right side, purl on the wrong side — which creates a smooth, flat surface ideal for showcasing colourwork motifs. Tension is measured over stocking stitch: 22 stitches and 30 rows to 10 cm (4 in) using 4.00mm (US 6) needles.
• Ribbing: As is typical for jumpers of this style, ribbed edgings are used at the cuffs, hem, and neckband to provide a neat, stretchy finish that holds its shape over time.

Materials – Yarn

The pattern is written specifically for Willow & Lark Poetry, a DK weight yarn sold in 50g / 1¾ oz balls. Poetry is a soft, knitter-friendly yarn well suited to children's garments. The design uses a total of six colours, with the main colour forming the background and five contrast colours creating the colourwork motifs:

• Baby Blue 610 (M – Main colour): 4–5 balls depending on size
• Clotted Cream 600 (A): 1 ball
• Lake Blue 611 (B): 1 ball
• Garnet 614 (C): 1 ball
• Buttercup 605 (D): 1 ball
• Hunter 607 (E): 1 ball

The combination of a soft blue background with cream, deep red, golden yellow, teal, and green accents gives the
