Interlace Cardigan in Rowan Cotton Cashmere – Crochet Pattern Summary

The Interlace pattern by Quail Studio is a downloadable PDF crochet pattern for a women's cardigan, published under the Rowan brand. Rated as advanced beginner level, it is an excellent next-step project for those who have mastered basic crochet stitches and are ready to explore simple lace-style construction. The design is worked in pieces — including a Left Front section detailed in the pattern — and assembled to create a finished, wearable cardigan with an open, airy texture.

What Is Being Made

The finished garment is a crochet cardigan featuring a lace-effect stitch pattern created through a combination of treble crochet stitches and chain spaces. The design is available in nine sizes, fitting chest measurements from 71–76 cm (28–30 in) up to 152–157 cm (60–62 in), with actual garment chest measurements ranging from 89.5 cm (35¼ in) to 169.5 cm (66¾ in), offering generous positive ease across all sizes. This inclusive size range makes the pattern accessible to a wide range of body types.

Techniques Used

• Foundation chain construction: Each section begins with a chain foundation, with the first row of double crochet worked directly into the chain. This is a standard flat-piece construction method.
• Flat, back-and-forth row crochet: The cardigan pieces are worked in rows, turning at the end of each row, rather than in the round. A chain-1 turning chain is used for double crochet rows, and a chain-3 turning chain counts as the first treble crochet in lace rows.
• Lace mesh construction: The signature stitch pattern is created by alternating treble crochet stitches with chain-1 spaces and skipped stitches, producing an open, interlaced mesh fabric that gives the design its name.
• Seaming and assembly: As a garment worked in separate pieces, the pattern involves joining finished sections together, a key skill for advancing crocheters.

Stitches Used

• Chain stitch (ch): Used for the foundation, turning chains, and to create the decorative open spaces within the lace pattern.
• Double crochet (dc): Used for the initial border or hem section of each piece, worked for approximately 2 cm before transitioning to the main lace pattern. In UK crochet terminology (used throughout this pattern), double crochet is equivalent to US single crochet.
• Treble crochet (tr): The primary structural stitch of the lace pattern rows, alternated with chain spaces to create the open mesh. In UK terminology, treble crochet is equivalent to US double crochet.
• Missed stitches: Deliberately skipping stitches in combination with chain spaces is central to forming the lace mesh, a technique that gives the fabric its characteristic lightness and drape.

Materials – Yarn

The pattern is designed specifically for Rowan Cotton Cashmere, a luxury yarn sold in 50 g balls. As the name suggests, this yarn blends the breathability and structure of cotton with the softness and warmth of cashmere, making it an ideal choice for a lightweight, wearable cardigan with beautiful stitch definition. Yarn quantities range from 7 balls for the smallest sizes up to 11 balls for the largest sizes.

Materials – Hook

The pattern calls for a 3.5 mm (US E/4) crochet hook. This relatively fine hook size is well suited to the lightweight Rowan Cotton Cashmere yarn and helps achieve the crisp, defined stitch structure needed for the lace mesh pattern to read clearly in the finished garment.
