Crochet Granny Square Blanket in Hayfield Bonus DK – Pattern Summary (CBBDK10274)

What You Are Making

This pattern guides you through crocheting a classic granny square blanket, a timeless and much-loved project in the world of crochet. The finished blanket is constructed by joining multiple individual granny squares together, creating a cosy, textured throw that is ideal for the home. Because the blanket is worked in separate squares that are then assembled, it is a wonderfully manageable project that can be picked up and put down with ease. This is a one-size design, making it straightforward to plan your project from start to finish.

Skill Level

This pattern is rated as beginner level, making it an excellent choice for those who are relatively new to crochet. While a basic familiarity with foundational crochet stitches is helpful, the repetitive, structured nature of the granny square format means that even newer crafters can build confidence and rhythm quickly. More experienced crocheters will also find this a satisfying and relaxing make.

Techniques Used

The core technique throughout this pattern is the construction of traditional granny squares, which are worked in the round from the centre outward. Each square is built up row by row in rounds, with stitches worked into chain spaces rather than individual stitches — a hallmark of classic granny square construction. The pattern features two distinct square designs:

• Square 1 – worked in a specific colour sequence using the designated shade combinations.
• Square 2 – worked in an alternative colour sequence, with all three rounds of the early stages worked in shade C, before transitioning to shade A. A total of 24 of these squares are made.

Working multiple square types and combining them introduces the crafter to simple colour sequencing and joining techniques, both of which are fundamental skills in crochet patchwork and modular construction.

Stitches Used

The pattern is written using UK crochet terminology throughout, with US equivalents provided in brackets. The following stitches and abbreviations are used:

• Chain (ch) – the foundational stitch used to begin rounds and create corner spaces.
• Slip stitch (ss) – used to join rounds and move yarn to new positions without adding height.
• Double crochet (dc) – known in US terms as single crochet; a short, tight stitch used for neat finishing.
• Treble (tr) – known in US terms as double crochet; the primary stitch used to build the body of each granny square, worked in clusters of three into chain spaces.
• Double treble (dtr) – known in US terms as treble; a taller stitch used at specific points in the pattern for shaping or decorative effect.

The granny square structure relies heavily on working groups of three treble stitches into one-chain spaces and two-chain corner spaces, creating the characteristic clustered, open-grid appearance. By the seventh round of each square, the stitch count reaches 80 stitches, giving each square a generous, well-defined size before joining.

Colour Shading

The pattern uses a three-colour system, referred to throughout as shade A, shade B, and shade C. The two square types each follow their own colour sequence, and by alternating between Square 1 and Square 2 across the blanket layout, a pleasing and cohesive colour arrangement is achieved in the finished throw. Colour changes are made between rounds, keeping the construction clean and manageable.
