Scarborough Cardigan in Rowan Summerlite DK – Crochet Pattern Summary

The Scarborough Cardigan is a beautifully designed crochet cardigan created by Lisa Richardson and published by Rowan. Available as a downloadable PDF, this pattern produces a lightweight, elegant cardigan worked in filet mesh fabric — a classic crochet technique that creates an open, lace-like fabric through a structured arrangement of solid and open blocks. The design is suitable for advanced beginner crocheters who are ready to work from a charted pattern and manage shaping across multiple sizes.

What Is Being Made

The finished project is a women's cardigan with set-in style sleeves and shaped fronts. The garment is constructed to fit a wide range of chest measurements, from 71–76 cm (28–30 in) up to 152–157 cm (60–62 in), offering nine sizes in total. The actual chest measurement of the finished garment ranges from 97 cm (38¼ in) to 181 cm (71¼ in), providing generous ease across the size range. The cardigan features distinct right and left fronts, a back, and sleeves that are shaped by working blocks in and out at specific rows according to the pattern chart.

Crochet Techniques Used

The primary construction technique throughout the Scarborough Cardigan is filet crochet, a method in which a grid-like mesh is formed using treble crochet stitches and chain spaces. In filet crochet, open blocks (mesh spaces) and solid blocks (filled with treble stitches) are arranged according to a chart to create pattern and texture. This technique gives the cardigan its characteristic airy, structured appearance.

The garment is worked in flat panels following a charted design. Shaping is achieved by missing blocks at the beginning of a row (by breaking yarn and rejoining at a later point) and by leaving blocks unworked at the end of a row, a technique commonly used in crochet to create clean, stepped decreases for sleeve and armhole shaping. The right front is worked by picking up stitches along the foundation chain of the shoulder and overarm seam, working into the other side of the foundation chain — a neat technique that creates a seamless-looking join.

Stitches Used

• Treble crochet (tr) – the primary structural stitch used to form both solid and open blocks in the filet mesh fabric
• Chain (ch) – used to form open mesh spaces within the filet pattern, as well as turning chains at the beginning of rows (3 ch counts as the first treble)
• Double crochet (dc) – referenced in the abbreviations, likely used for edgings or finishing details
• Slip stitch (ss) – referenced in the abbreviations, typically used for joining or neat finishing

The tension for the pattern is stated as 20 stitches and 9½ rows to 10 cm measured over filet mesh fabric. Achieving this tension is important for ensuring the finished cardigan matches the stated measurements across all nine sizes.

Materials

The pattern calls for Rowan Summerlite DK, a DK weight yarn sold in 50 g balls. The photographed sample was made in Mushroom 454, a warm, neutral shade that highlights the delicate filet mesh texture beautifully. The quantity required varies by size, ranging from 7 to 15 balls depending on the size being made.

The recommended tool is a 3.50 mm (no. 9) (US E4) crochet hook, which is used throughout the entire garment. Rowan Summerlite DK is a yarn particularly well suited to warm-weather garments, making the Scarborough Cardigan an ideal choice for spring and summer layering.
