Sweater in Sirdar Boufflé 7507 – Easy Crochet Pattern for Sizes 32/34 to 52/54 Inches

This downloadable PDF crochet pattern from Sirdar provides full instructions for crocheting a relaxed, textured sweater using Sirdar Boufflé yarn. Labelled as an easy crochet project, this design is well-suited to confident beginners and intermediate crocheters who want to create a cosy, stylish pullover with interesting stitch detail. The pattern is notably inclusive, covering six sizes from 32/34 inches to 52/54 inches bust measurement, with actual finished measurements ranging from 91 cm (36 inches) up to 141 cm (55½ inches), making it accessible to a wide range of body types.

What Is Being Made

The finished project is a crocheted sweater featuring long sleeves and a structured body. It is worked in pieces — a back, a front, and sleeves — which are then seamed together. The sweater has a full length ranging from 60 cm to 73 cm depending on size, and a sleeve length of approximately 46 to 48 cm, noted as adjustable so makers can customise the fit. The silhouette is classic and relaxed, with shaped armholes adding a neat, fitted finish at the shoulder.

Techniques Used

• Foundation chain construction – each piece begins with a foundation chain worked to the appropriate number of stitches for the chosen size
• Iced Shell Pattern – a decorative repeating stitch pattern that forms the main fabric of the sweater, creating a soft, textured shell effect across the body and sleeves
• Treble and Double Crochet combination pattern – used alongside or in transition with the shell pattern to build structure and shape
• Armhole shaping – worked using decrease techniques to create a neat armhole opening, ensuring the sweater fits correctly at the shoulder
• Tr2tog decrease – a specific two-treble-together decrease stitch used during armhole shaping, worked by inserting the hook into successive stitches and drawing through loops in sequence to reduce stitch count cleanly
• Turning chains – used at the start of rows to maintain correct height, with the pattern specifying whether the turning chain counts as a stitch
• Seaming – the completed pieces are joined to form the finished sweater

Stitches Used

• Double crochet (dc) – a short, tight stitch used in the foundation row and as part of the Iced Shell Pattern
• Treble (tr) – a taller stitch forming the main body of the shell and structural rows
• Chain (ch) – used to create spaces within the Iced Shell Pattern and as turning chains at row beginnings
• Slip stitch (ss) – used for joining and finishing
• Tr2tog – a paired treble decrease stitch worked over two stitches, drawing through three loops on the final step to reduce width during armhole shaping

Tension

The pattern specifies two tension gauges to check before beginning. The Iced Shell Pattern should measure 12 stitches and 7 rows to 10 cm (4 inches), while the Treble and Double Crochet pattern should measure 19 stitches and 10 rows to 20 cm (8 inches). Both are measured using a 6.50 mm crochet hook (UK size 3, US size K/10.5). The pattern strongly emphasises that achieving the correct tension is essential for the sweater to come out at the correct measurements. If your tension produces fewer stitches than stated, switch to a thinner hook; if more stitches, use a thicker hook.
