Rowan Hahana Jumper Crochet Pattern

Rowan Hahana Crochet Sweater by Lisa Richardson

What is Being Made

The Rowan Hahana is a lightweight crochet sweater designed to fit bust measurements ranging from 81-127 cm (32-50 inches). This garment is crafted using Rowan Summerlite 4ply yarn and features an elegant lace construction, making it an ideal project for warm-weather wear. The pattern includes five size options to accommodate various body measurements, with the actual finished bust measurements ranging from 89-133 cm (35-52½ inches).

Techniques Used

This sweater is constructed using several key crochet techniques that create both structure and visual interest:

• Bottom-up construction: The garment is worked from the bottom edge upward, allowing for easy fitting adjustments and straightforward shaping
• Flat pieces: The sweater is worked flat in separate pieces rather than in the round, which are then seamed together for a finished garment
• Lace patterning: An intricate lace pattern forms the primary design element, created through strategic placement of chain spaces and treble stitches that create openwork sections
• Seaming: Individual flat pieces are joined together using seaming techniques to create the complete sweater
• Armhole shaping: The pattern includes specific shaping instructions for the armholes, worked by decreasing stitches and adjusting pattern repeats to create a fitted sleeve opening

Stitches Used

The Hahana pattern employs fundamental crochet stitches combined to create the lace effect:

• Double crochet (dc): Used as a foundational stitch throughout the pattern, particularly in solid sections and pattern edges
• Treble crochet (tr): Creates the vertical elements within the lace pattern, often worked in groups of three to form decorative clusters
• Double treble (dtr): Appears in the pattern structure, adding height and definition to certain sections
• Chain stitches (ch): Form the openwork spaces characteristic of the lace design, with 3-chain and 5-chain sequences creating the pattern's negative space
• Slip stitch (ss): Used for joining and shaping, particularly when decreasing for armholes

Pattern Repeat and Stitch Sequence

The lace pattern is created through a four-row repeat that establishes the characteristic openwork design. The pattern alternates between rows featuring treble clusters separated by chain spaces and rows of double crochet stitches that anchor the lace sections. Tension is critical for this design, with the pattern requiring 3 pattern repeats to measure 9.5 cm and 12 rows to measure 10 cm when worked with the specified crochet hook.

Materials Required

The Rowan Hahana requires specific materials to achieve the intended drape and appearance:

• Yarn: Rowan Summerlite 4ply, a lightweight four-ply yarn suitable for delicate lace work. The pattern requires between 5-7 balls of 50-gram weight depending on size selection. The photographed sample is shown in Still Grey 422
• Crochet hook: 3.00mm (US size C2/D3) crochet hook for working the main pattern
• Notions: Standard finishing materials for seaming and weaving in ends

Skill Level and Construction Notes

This pattern is designed for crocheters with intermediate skills, as it requires understanding of lace pattern reading, tension maintenance, and shaping techniques. The bottom-up, flat construction method provides good control over fit, and the seamed construction allows for precise finishing. The pattern includes detailed row-by-row instructions for shaping the armholes and completing the garment, with pattern repeats clearly marked for easy tracking throughout the project.
