Sirdar Cotton DK Crochet Jackets – Pattern 7071: Complete Guide

Pattern 7071 from Sirdar is a downloadable PDF crochet pattern featuring two stylish jacket designs — a Short Jacket and a Long Jacket — both worked in Sirdar Cotton DK. The pattern is inclusive, covering six sizes ranging from a 32/34 inch to a 52/54 inch bust, making it accessible to a wide range of crocheters. Both jackets share the same construction approach but differ in finished length, giving crafters a choice between a cropped, casual silhouette and a more relaxed, longer style.

Designs Included

Short Jacket

The Short Jacket is worked in Sirdar Cotton DK shade 516 and has a finished full length of approximately 55 to 68 cm (21¾ to 26¾ inches) depending on size. It requires between 6 and 9 balls of Sirdar F039 Cotton DK in 100g balls. This version is ideal for layering over summer tops or wearing as a lightweight cover-up, offering a neat, tailored finish without excess bulk.

Long Jacket

The Long Jacket is worked in Sirdar Cotton DK shade 505 and measures approximately 65 to 78 cm (25½ to 30¾ inches) in full length. Yarn requirements range from 6 to 10 balls of Sirdar F039 Cotton DK in 100g balls. The longer hem creates a more flowing, relaxed silhouette that works beautifully as a transitional layer or a lightweight summer jacket.

Sizing and Fit

Both jackets are designed to fit bust measurements of 81/86 cm through to 132/137 cm (32/34 to 52/54 inches), with actual garment measurements ranging from 89 cm to 145 cm (35 to 57¼ inches), providing a comfortable, slightly eased fit. Sleeve length is consistent across both designs at approximately 46 to 48 cm (18 to 19 inches) and is noted as adjustable, allowing crocheters to customise the fit further.

Techniques and Stitches Used

Both jackets make use of a combination of crochet techniques and stitch patterns, creating visual interest and texture throughout the garment. The pattern draws on three distinct stitch structures:

• Medallion pattern — a decorative, repeating motif that forms the main body fabric, worked over a repeat of 16 stitches and 4 rows
• Treble crochet (tr) — used for structural sections of the jacket, worked in rows to build fabric with good drape
• Double crochet (dc) — used for finishing and edging sections, creating a firm, neat border

A key technique featured in this pattern is the Tr5tog (treble 5 together) decrease stitch, which involves working five treble stitches together by drawing through all loops at once. This stitch is central to the medallion pattern and creates the characteristic gathered, lace-like texture seen throughout the jacket body. Crocheters should be comfortable working yarn over hook (yoh) sequences and managing multiple loops on the hook simultaneously.

Additional techniques include working into chain spaces, using slip stitches (ss) for joining, and managing shaping through increases. The pattern also incorporates chain (ch) sequences to create openwork effects within the medallion repeat, contributing to the lightweight, breathable quality of the finished fabric — ideal for a cotton summer garment.
