Hats and Scarves in Sirdar Crofter DK – Pattern 7906: Complete Crochet Guide

Pattern 7906 from Sirdar is a downloadable PDF crochet pattern offering four coordinating accessories: a Treble Pattern Hat, a Treble Pattern Scarf, a Ridge Pattern Hat, and a Ridge Pattern Scarf. All four designs are worked in Sirdar Crofter DK yarn, a self-striping double knitting weight that adds effortless colour interest without any yarn changes. The pattern is rated intermediate in difficulty, making it an ideal project for crocheters who are comfortable with basic stitches and ready to explore cluster techniques and post stitches.

Yarn and Materials

All designs use Sirdar Crofter DK, worked with a 4.00mm (UK 8 / US F/5) crochet hook as the primary tool. The Ridge Pattern Scarf also calls for a 5.00mm (UK 6 / US H/8) crochet hook, making it the only design in the set to require two hook sizes. The yarn quantities are modest:

• Treble Pattern Hat: 1 × 50g ball of Sirdar Crofter DK shade 100
• Treble Pattern Scarf: 3 × 50g balls of Sirdar Crofter DK shade 100
• Ridge Pattern Hat: 1 × 50g ball of Sirdar Crofter DK shade 099
• Ridge Pattern Scarf: 3 × 50g balls of Sirdar Crofter DK shade 099

The two colourways — shade 100 and shade 099 — give each pair of hat and scarf its own distinct look while sharing the same construction logic. Yarn quantities are based on achieving the specified tension with the recommended yarn.

Tension

The stated tension is 16 stitches and 19 rows to 10cm (4 inches) over the stitch pattern using the 4.00mm hook. Achieving correct tension is important for the hats in particular, as they are sized to fit an average adult head and rely on accurate stitch counts for a proper fit.

Finished Measurements

• Hats: Sized to fit an average adult woman's head
• Treble Pattern Scarf: Approximately 16 cm × 150 cm (6¼ × 59 inches)
• Ridge Pattern Scarf: Approximately 18 cm × 150 cm (7 × 59 inches)

Treble Pattern Hat and Scarf

The Treble Pattern Hat is worked in the round, beginning with a foundation of 32 double crochet stitches and building upward using a repeating structure of treble clusters set into chain spaces. The pattern uses a 3-chain turning equivalent (counting as 1 treble and 1 chain), with tr3cl (treble 3-cluster) stitches worked into the chain spaces of the previous round. Alternate rounds of plain double crochet keep the fabric structured and help the cluster motifs stand out clearly.

A treble cluster (tr3cl) is a classic crochet technique in which multiple incomplete treble stitches are worked into the same stitch or space and then closed together at the top, creating a raised, bobble-like texture. This gives the Treble Pattern designs a visually rich, dimensional surface that is enhanced further by the colour gradients of Sirdar Crofter DK.

The Treble Pattern Scarf uses the same stitch vocabulary as the hat, worked flat to produce a long, textured strip measuring approximately 16 cm wide and 150 cm long.
