Scallop Shell Yoke Sweater Jumper Knitting Pattern

Scallop Shell Yoke Sweater in Sirdar Loveful 100% Bio Blend

What is Being Made

This is an intermediate-level knitted sweater featuring a distinctive scallop shell yoke design. The garment is available in seven sizes ranging from XS (71–76 cm chest) through XXXL (132–137 cm chest), making it suitable for a wide range of body measurements. The sweater combines contemporary knitwear design with nature-inspired details, specifically drawing aesthetic inspiration from shell structures as part of the Sirdar Loveful collection's broader design philosophy.

Design Details and Inspiration

The scallop shell yoke serves as the primary design feature, creating visual interest at the upper body and shoulders. This design element reflects Sirdar's modern approach to knitwear, where the collection draws inspiration from natural forms including cell structures, beehives, and shells. The pattern is identified as Design No. 10908 and is classified as intermediate difficulty, indicating that knitters with foundational skills and experience with basic shaping techniques will find this project achievable.

Knitting Techniques and Stitches

The sweater is constructed using double knitting, a fundamental knitting technique that creates a dense, structured fabric with excellent drape and durability. Double knitting involves working with yarn at a specific weight classification, allowing knitters to produce garments with consistent stitch definition and professional finish. The yoke shaping employs techniques typical of top-down or yoke-based sweater construction, where decreases are strategically placed to create the scallop shell pattern effect at the neckline and shoulder areas. This approach provides excellent fit customization and allows knitters to try on the garment as they work.

Materials: Yarn and Needles

This pattern is designed specifically for Sirdar Loveful Bio Blend Double Knitting yarn. The Loveful Bio Blend represents a significant innovation in sustainable yarn production, incorporating award-winning CiCLO® technology—a recycled polyester component blended with natural wool fibers. This hybrid composition delivers both environmental benefits and practical performance. The CiCLO® recycled polyester is engineered to biodegrade similarly to wool at the end of the garment's life, thereby reducing microplastic pollution in aquatic environments. The yarn is available in a vibrant colour palette inspired by nature-based design principles, with the pattern sample shown in shade 107.

Double knitting yarn requires appropriately sized needles to achieve proper gauge and fabric density. Knitters should refer to the specific needle size recommendations provided within the pattern instructions, which will be calibrated to produce the correct finished measurements across all seven size options.

Size Range and Finished Measurements

• XS: 71–76 cm (28–30") chest, 86 cm (34") width, 56 cm (22") full length
• S: 81–86 cm (32–34") chest, 96 cm (37¾") width, 58 cm (22¾") full length
• M: 91–97 cm (36–38") chest, 107 cm (42") width, 60 cm (23¾") full length
• L: 102–107 cm (40–42") chest, 117 cm (46") width, 62 cm (24½") full length
• XL: 112–117 cm (44–46") chest, 127 cm (50") width, 64 cm (25¼") full length
• XXL: 122–127 cm (48–50") chest, 137 cm (54") width, 66 cm (26") full length
• XXXL: 132–137 cm (52–54") chest, 147 cm (58") width, 68 cm (26¾") full length

Sleeve length remains consistent across most sizes at approximately 45–48 cm (approximately 18–19"), with minimal variation to accommodate different arm proportions proportionally.

Yarn Sustainability and Performance

Sirdar Loveful Bio Blend yarn represents a commitment to sustainable hand knitting without compromising on quality or wearability. The yarn is engineered to perform like traditional knitting yarns during the garment's useful life, withstanding regular washing and wearing just as any conventional Sirdar yarn would. The integration of CiCLO® recycled polyester technology means that when the sweater eventually reaches the end of its life cycle, the recycled polyester component will biodegrade similarly to natural wool, significantly reducing environmental impact compared to conventional synthetic fibres that persist
