Sirdar Cotton DK Crochet Cardigan and Waistcoat – Pattern 7072

This downloadable PDF crochet pattern from Sirdar includes instructions for two classic wardrobe essentials: a long-sleeved Cardigan and a sleeveless Waistcoat, both worked in Sirdar Cotton DK. The pattern is size-inclusive, covering six sizes to fit bust measurements from 81/86 cm (32/34 in) up to 132/137 cm (52/54 in), making it an excellent choice for a wide range of crocheters. Both garments feature elegant stitch detailing that balances structure with delicate texture, creating pieces that are equally suited to warm-weather layering or transitional dressing.

The Cardigan

The Cardigan is a relaxed, wearable design with set-in or shaped sleeves and a neat, finished silhouette. Actual finished bust measurements range from 87 cm (34¼ in) to 140 cm (55¼ in), with a full length of 54 cm to 67 cm (21¼ in to 26½ in) depending on size. The sleeve length is approximately 46–48 cm (18–19 in) and is noted as adjustable, giving crocheters flexibility to customise the fit.

Materials for the Cardigan

• Yarn: Sirdar Cotton DK in shade 512, requiring 5 to 8 x 100g balls depending on size
• Hook: 4.00mm (UK 8 / USA F/5) crochet hook
• Notions: 1 button

The Waistcoat

The Waistcoat is a versatile, sleeveless companion piece that uses the same stitch patterns and construction approach as the Cardigan, making it a great standalone project or a coordinating layer. Its shorter yarn requirement makes it an approachable project for those newer to garment crochet or working with a limited stash.

• Hook: 4.00mm (UK 8 / USA F/5) crochet hook

Stitches and Techniques Used

Both garments are worked in crochet and feature a combination of two beautifully complementary stitch patterns that give the designs their distinctive decorative character.

Flower Panel Pattern

The Flower Panel is a key decorative feature of both designs. It is constructed using a combination of treble crochet (tr), chain spaces (ch sp), and a distinctive 3tr picot detail. The picot is formed by working one treble, then three chain stitches, inserting the hook down through the top of the treble just worked, and closing with a slip stitch — this is repeated three times to create a small, neat raised cluster that adds a floral, vintage-inspired texture to the fabric. Tension for the Flower Panel is measured as 2 flower panels and 18 stitches over 9 cm (3½ in) on the 4.00mm hook.

Trellis Pattern

The Trellis Pattern forms the main body fabric of both garments. This is an open, lacy mesh construction worked using treble crochet, chain spaces, and strategic miss stitches to create a repeating diagonal or grid-like lattice effect. The trellis stitch is a classic crochet technique that produces a lightweight, breathable fabric — ideal for cotton yarn. Tension for the Trellis Pattern is 19 stitches and 9 rows to 10 cm (4 in).
