"Toby Jumper" - Jumper Knitting Pattern For Men in Debbie Bliss Aymara - DB217

Toby Jumper – Men's Knitting Pattern by Debbie Bliss in Aymara Yarn

The Toby Jumper is a classic men's knitted sweater pattern designed by Debbie Bliss, worked in her own Aymara yarn. This is a substantial, well-structured garment that combines clean shaping with stripe detailing, making it a rewarding project for the experienced knitter. The pattern is available as a downloadable PDF and covers five sizes to fit a wide range of chest measurements.

Sizing and Finished Measurements

The Toby Jumper is offered in five sizes designed to fit chest measurements ranging from 81–86 cm (32–34 in) up to 122–127 cm (48–50 in). The finished chest measurements are generously cut, running from 93 cm (36½ in) through to 133 cm (52½ in), providing a comfortable, relaxed fit. Length to shoulder ranges from 65 cm (25½ in) to 72 cm (28¼ in) depending on size, and sleeve length runs from 48 cm (19 in) to 50 cm (19¾ in). The pattern includes both a back and front, plus sleeves, with schematic measurements provided for each piece.

What Is Being Made

The finished garment is a full-length men's jumper (sweater) with set-in or structured sleeves. It features a classic silhouette suited to everyday wear, with stripe patterning adding visual interest across the body and sleeves. The design is practical and wearable while still offering enough technical challenge to engage an advanced knitter.

Construction Techniques

The Toby Jumper is constructed using the following key techniques:

• Bottom-up construction: The garment pieces are worked from the cast-on edge upward toward the shoulders, which is the traditional approach for seamed sweaters and gives the knitter excellent control over length adjustments.
• Worked flat: All pieces — back, front, and sleeves — are knitted flat on straight or circular needles, producing separate panels rather than working in the round.
• Seamed finishing: The individual flat-knitted pieces are joined together using seaming techniques, creating a structured garment with neat, durable seams that help the jumper hold its shape over time.
• Stripes: The design incorporates stripe patterning, which requires careful colour management and neat yarn joining or carrying to keep the wrong side tidy.

Stitches Used

The pattern makes use of a range of knitting stitches and techniques, including:

• Stocking stitch (stockinette stitch) – the primary fabric stitch, creating a smooth knit face and a purl reverse, used across the main body of the jumper.
• Moss stitch (seed stitch) – an alternating knit and purl stitch that creates a textured, non-curling fabric, typically used for borders, cuffs, or neckbands.
• kfb (knit into front and back) – a common increase stitch used for shaping.
• pfb (purl into front and back) – a purl-side increase used where shaping occurs on wrong-side rows.
• skpo (slip 1, knit 1, pass slipped stitch over) – a left-leaning decrease used in shaping.
• ssk (slip, slip, knit) – another left-leaning decrease, worked by slipping two stitches knitwise before knitting them together through the back loops.
• psso (pass slipped stitch over) – used in combination with other stitches for decreasing.
• yon / yf / yrn / y2rn – various yarn-over techniques used to create yarn-forward movements or decorative increases as required by the pattern.
