• Buttons: 8 x TGB4456 wooden buttons, 12mm, from Textile Garden

Techniques and Construction

The Whitby Cardigan is constructed using a combination of straightforward and intermediate crochet shaping techniques. While the primary stitch is simple to learn, the shaping methods used throughout the pattern — particularly at the armholes, shoulders, and back neck — introduce the crocheter to more advanced construction skills, making this an ideal project for someone progressing beyond complete beginner level.

Key Techniques Used

• Armhole shaping: Worked using slip stitches at the beginning of rows to set aside stitches, combined with turning mid-row to create clean, stepped decreases
• Decrease shaping: Uses both htr2tog (half treble crochet two together) and htr3tog (half treble crochet three together) to reduce stitch counts smoothly at row ends
• Single stitch decreases: Worked at row beginnings by missing the stitch at the base of the turning chain, and at row ends using htr2tog, for gradual, refined shaping
• Shoulder and back neck shaping: Worked using the same shaping methods as the armhole, maintaining consistency throughout the garment construction
• Straight sections: Worked without shaping once armhole decreases are complete, continuing until the armhole reaches the required depth for each size

Stitches Used

• Half treble crochet (htr): The primary stitch used throughout the body of the cardigan, creating a dense yet flexible fabric with excellent drape in the fine 4 ply yarn
