Poppet Jumper - Free Knitting Pattern For Babies in Paintbox Yarns Baby DK Prints by Paintbox Yarns

Poppet Jumper – Free Baby Knitting Pattern by Paintbox Yarns in Baby DK Prints

The Poppet Jumper is a charming, free downloadable knitting pattern designed by Paintbox Yarns for babies aged 0–3 months through 18–24 months. This adorable little sweater is worked at an intermediate difficulty level, making it an ideal project for knitters who have moved beyond the basics and are ready to tackle shaping, seaming, and buttonholes. The finished jumper is a classic, wearable baby garment with a neat, structured silhouette that suits both everyday wear and special occasions.

What Is Being Made

The Poppet Jumper is a knitted baby sweater — sometimes called a jumper in British terminology — sized to fit chest measurements ranging from 16 inches (41 cm) up to 24 inches (61 cm), corresponding to the five baby age brackets listed above. The finished chest measurements of the garment itself range from 18¼ inches (46.5 cm) to 26¾ inches (68 cm), providing a comfortable, slightly eased fit. The body length ranges from 8½ inches (22 cm) to 15¼ inches (39 cm), and the sleeve length ranges from 4¾ inches (12 cm) to 10½ inches (27 cm), growing proportionally with each size so the jumper maintains its balanced proportions across the full size range.

Construction and Techniques

This pattern uses a bottom-up, worked-flat, seamed construction method. Working flat means each piece — the front, back, and sleeves — is knitted back and forth in rows on straight or circular needles rather than in the round. Once all pieces are complete, they are joined together using seaming, which gives the finished garment a clean, structured finish with defined edges. This approach is particularly well-suited to baby garments, as seams add a small amount of structure and durability to pieces that will be laundered frequently.

• Bottom-up construction: Knitting begins at the lower hem of the body and works upward toward the shoulders, allowing the knitter to easily adjust length before committing to the armhole shaping.
• Worked flat: All pieces are knitted in rows, producing a fabric with right-side and wrong-side rows, which is the traditional method for seamed garments.
• Seamed finishing: The individual pieces are sewn together after knitting, creating neat, stable seams at the shoulders, sides, and sleeve joins.
• Buttonholes: The pattern incorporates buttonhole construction, adding a practical button opening — typical on baby jumpers for easy dressing and undressing.
• Buttons: Buttons are used as a functional and decorative closure, a classic detail on baby knitwear that also makes the garment easier to put on over a baby's head.

Stitches Used

As an intermediate-level pattern, the Poppet Jumper draws on a combination of foundational and slightly more advanced knitting stitches and techniques. Knitters can expect to work with:

• Knit and purl stitches — the building blocks of all flat knitting, used to create the main fabric of the jumper body and sleeves.
• Ribbing — typically a combination of knit and purl stitches worked in a repeating sequence (such as 1×1 or 2×2 rib), commonly used at hems, cuffs, and neckbands to create a stretchy, neat border that holds its shape against the body.
• Increases and decreases — used during sleeve shaping and armhole shaping to add or remove stitches and create the fitted, tapered silhouette of the garment.
• Buttonhole stitches — a specific technique worked over one or two rows to create a small, neat opening in the fabric through which a button can pass.

Yarn and Materials

This pattern is designed specifically for Paintbox Yarns Baby DK Prints, a DK weight yarn from the Paintbox Yarns brand. DK (double knitting) weight is a light-to-medium yarn that knits up quickly while still producing a fine, soft fabric — an
