String Heidi Pullover Jumper Knitting Pattern

String Heidi Pullover: Merino Wool and Cashmere Knit Sweater

What Is Being Made

The String Heidi Pullover is a classic knitted sweater designed by Lidia Karabinech, available in five sizes ranging from Small to XXL. This pullover features a contemporary construction method using modular geometric shapes, creating a distinctive visual and structural design. The finished bust measurements range from 37½ inches (95.5 cm) in size Small to 54 inches (137 cm) in size XXL, with corresponding lengths from 20¼ inches (51.5 cm) to 25¼ inches (64 cm).

Knitting Techniques

The Heidi Pullover employs a bottom-up construction method combined with seamed and in-the-round knitting. The sweater is built using a modular approach featuring multiple tiers of rectangles that are strategically picked up and worked to create the garment's structure. The pattern uses a two-tier rectangle system: the First Tier of Rectangles is worked by picking up stitches from a Base Triangle, and the Second Tier of Rectangles is subsequently worked by picking up stitches from the First Tier. This geometric construction method allows for precise shaping and creates interesting textural variation throughout the piece.

The body is worked in the round using circular needles, which eliminates the need for seaming on the main body sections. The neckband is worked separately in the round using a smaller circular needle, then integrated into the finished garment. This combination of techniques results in a professionally finished sweater with minimal seaming while maintaining structural integrity.

Stitches Used

• Stockinette Stitch (St st) – The primary stitch used throughout the body of the sweater, worked flat in rows during the rectangle sections and in the round for the main body sections. Stockinette creates a smooth, classic fabric with a distinctive V-pattern on the right side.
• Stockinette Stitch in the round (St st) – Used when working circularly, requiring only knit stitches on every round to create the same smooth fabric as flat stockinette.
• K1, P1 Rib – Applied to the neckband in both flat and in-the-round variations. This elastic rib stitch creates a fitted, stretchy edge that hugs the neck comfortably and prevents curling.
• Decrease stitches (ssk and p2tog) – Used strategically throughout the rectangle sections to shape the garment and integrate new tiers of stitches into the existing fabric.

Materials and Gauge

The Heidi Pullover is designed to be knitted with STRING OSLO yarn, a premium blend of 70% merino wool and 30% cashmere. This luxurious fiber combination provides softness, breathability, and warmth. The yarn is supplied in balls of 1.75 ounces (50 grams) with 155 yards (142 meters) per ball. The color specified in the pattern is 724906 White/Black. Yardage requirements range from 6 balls for size Small to 10 balls for size XXL.

Knitting needles required include one size 9 (5.5 mm) circular needle measuring 32 inches (80 cm) long for the main body, and one size 9 (4 mm) circular needle measuring 16 inches (40 cm) long specifically for the neckband. Needle size may be adjusted to obtain the correct gauge. Additional notions include stitch markers for tracking pattern repeats and shaping points, and stitch holders for temporarily securing stitches during construction.

The pattern gauge is 15 stitches and 20 rows over 4 inches (10 cm) in Stockinette Stitch. Achieving the correct gauge is essential for obtaining the specified finished measurements and proper fit. Knitters are advised to knit a gauge swatch before beginning the project to ensure their tension matches the pattern requirements.
