Astilbe Sweater Jumper Knitting Pattern

Astilbe Sweater in Rowan Handknit Cotton

What is Being Made

The Astilbe Sweater is a knitted pullover garment designed to fit chest measurements ranging from 71-76 cm (28-30 inches) through 152-157 cm (60-62 inches), offering nine size options for inclusive fit. This sweater features a structured construction with distinct lower and upper body panels, creating visual interest and textural variation throughout the finished piece.

Techniques Used

This advanced beginner knitting project employs several intermediate techniques to achieve its sophisticated appearance. The sweater utilizes pick-up-and-knit construction, where stitches are picked up along the side edges of the lower panel to create the upper body section. This method allows for seamless integration between garment sections and is worked with the right side facing.

The design incorporates shaped neckline shaping through strategic cast-offs and decreases. The front neck shaping involves casting off 2 stitches at the beginning of alternate rows over multiple rows, followed by single stitch decreases worked at the neck edge on subsequent rows. The pattern accounts for size-specific variations in shaping sequences, with different sizing groups following customized decrease schedules to ensure proper fit across the full range.

Blocking is an essential finishing technique for this garment, as the tension measurement is specifically noted as "once blocked," indicating that proper wet or steam blocking is necessary to achieve the intended dimensions and drape of the finished sweater.

Stitches Used

• Garter Stitch (g st) — A fundamental knit stitch created by knitting every row, producing a reversible fabric with horizontal ridges. In the Astilbe Sweater, garter stitch is used strategically in the lower panel and as a textural contrast section within the upper body panel.
• Stockinette Stitch (st st) — The most common knit fabric, created by alternating knit rows on the right side with purl rows on the wrong side. This stitch produces a smooth, flat surface and forms the primary fabric of the upper body sections.
• Textured Pattern — The pattern references a textured stitch pattern used for tension measurement, suggesting the sweater incorporates a more complex stitch combination beyond basic stockinette and garter stitches to create visual depth and interest.

Materials

The Astilbe Sweater is knitted using Rowan Handknit Cotton, a natural fiber yarn supplied in 50-gram balls. The photographed sample is worked in the colorway Celery 309. Yarn quantities range from 15 to 19 balls depending on the chosen size, with larger sizes requiring proportionally more yardage.

The project requires two pairs of needles: 3.25mm (US 3) needles for ribbed or elastic sections, and 4mm (US 6) needles for the main fabric. Additional notions include stitch holders for managing stitches during construction (particularly essential for the front neck shaping) and stitch markers to track pattern repeats and shaping points.

Tension and Fit

The specified tension is 20 stitches and 36 rows to 10 centimeters, measured over the textured pattern using 4mm needles after blocking. Achieving correct tension is critical for this garment, as the sizing chart provides actual chest measurements for each finished size, allowing knitters to select the appropriate size based on desired fit rather than body measurements alone.
