Sirdar Diamond Trellis Cardigan Knitting Pattern

Sirdar Diamond Trellis Cardigan

What Is Being Made

The Sirdar Diamond Trellis Cardigan (Design No. 10212) is an advanced-level knitted cardigan designed for sophisticated womenswear. This garment is available in six sizes ranging from 81cm to 137cm chest measurements (32 inches to 54 inches), making it suitable for a wide range of body types. The cardigan features a classic silhouette with full-length sleeves and is crafted to deliver a luxurious, designer-quality appearance at an accessible price point.

Techniques and Construction

This is an advanced knitting project that employs the diamond trellis stitch pattern as its defining design element. The pattern requires careful attention to stitch placement and tension to achieve the intricate lattice effect that gives the cardigan its distinctive visual appeal. The construction involves knitting separate pieces—back, front panels, and sleeves—which are then assembled together. The pattern instructions provide detailed guidance for each size, with the Sirdar quality guarantee that the pattern has been triple-checked to ensure success when worked in the recommended yarn.

Stitches Used

While the specific stitch abbreviations are referenced in the full pattern instructions on the back page of the PDF, the diamond trellis design employs a combination of knit and purl stitches arranged to create an openwork lattice pattern. This technique requires intermediate to advanced knitting skills, as maintaining consistent tension and accurate stitch counts across the trellis motif is essential for the pattern to display correctly. The cardigan construction likely incorporates ribbing at the cuffs, hem, and button bands for a finished, professional appearance.

Materials: Yarn and Needles

The Sirdar Diamond Trellis Cardigan is designed to be worked in Sirdar Cashmere Merino Silk, a luxury yarn blend available in Double Knitting (DK) weight. This yarn combines pure silk, extra fine merino wool, and Himalayan cashmere, creating a soft, sophisticated fiber ideal for elegant womenswear. The specific colorway featured is shade 415 Polished Copper, though alternative shades are available including Old Gold (409), Sand Stone (422), and Orchard Red (416).

Yarn quantities vary by size:

• Size S (81/86cm): 15 balls of 50g
• Size M (91/97cm): 16 balls of 50g
• Size L (102/107cm): 18 balls of 50g
• Size XL (112/117cm): 20 balls of 50g
• Size XXL (122/127cm): 21 balls of 50g
• Size XXXL (132/137cm): 22 balls of 50g

The pattern requires two pairs of knitting needles: one pair of 4mm (UK size 8 / USA size 6) needles for the main fabric and one pair of 3¼mm (UK size 10 / USA size 3) needles for ribbed edgings. The needle size progression creates the proper gauge and fabric density necessary for the diamond trellis stitch to display beautifully while maintaining the drape and structure appropriate for a cardigan in this luxury yarn.

The cardigan is designed with the following finished measurements across the size range:

• Chest width: 81cm to 137cm (32 inches to 54 inches)
