Evelyn Jumper Crochet Pattern

Evelyn Jumper in Rowan Big Wool

What is Being Made

The Evelyn Jumper is a crochet sweater designed by Emma Wright, available in three sizes to fit bust measurements of 71–97cm (28–38in), 102–127cm (40–50in), and 132–157cm (52–62in). The finished garment features actual bust measurements of 102cm (40¼in), 136cm (53½in), and 170cm (67in) respectively. This intermediate-level crochet project creates a colorful, patterned jumper using a modular construction method.

Construction Technique

The Evelyn Jumper is constructed using a granny square modular method, a classic crochet technique that builds the garment from individual geometric units that are then joined together. This approach allows crafters to work on manageable sections before assembling the complete sweater. The pattern requires making 18, 22, or 26 half granny squares depending on size, plus 4 quarter granny squares for shaping and finishing details. Squares are joined using the slip stitch method, creating a cohesive fabric with visible geometric patterning.

Stitches and Stitch Details

The pattern employs fundamental crochet stitches including:

• Treble stitches (tr) – used in the foundation rows of the granny squares
• Double crochet stitches (dc) – the primary stitch used throughout most of the square construction
• Chain stitches (ch) – used to create spaces and structural elements
• Slip stitches (sl st) – used to join chains into rings and to join completed squares together

The pattern uses chain spaces (ch-sp) as a key design element, with rows building progressively from 3 chain spaces in Row 1 to 7 chain spaces by Row 3, creating the characteristic open, lacy structure of granny squares. Each completed full granny square measures approximately 17cm × 17cm across the diagonals when joined.

Materials: Yarn and Hooks

The Evelyn Jumper is worked in Rowan Big Wool, a bulky-weight yarn supplied in 100-gram balls. The pattern uses a 10mm (US 15) crochet hook throughout. Four colors of Big Wool are required:

• Color A: Biscotti 082 – 8, 10, or 12 balls depending on size
• Color B: Black 008 – 2, 3, or 3 balls depending on size
• Color C: Glum 056 – 2, 3, or 3 balls depending on size
• Color D: White Hot 001 – 2, 2, or 3 balls depending on size

Tension and Gauge

The recommended tension is 9 double crochet stitches × 11 double crochet rows to 10cm (4in) when working with a 10mm (US 15) crochet hook. Achieving correct tension is essential for obtaining the proper finished measurements and ensuring the granny squares are the correct size before joining.

Skill Level

This pattern is rated as intermediate difficulty, suitable for crocheters with foundational knowledge of basic stitches and techniques. The modular construction and color changes add complexity beyond beginner projects, but the repetitive nature of working multiple identical granny squares makes the pattern accessible to those building their skills.
