Geometric Crochet Baby Blanket in Bernat Pop! by Bhooked Crochet

This Geometric Crochet Baby Blanket is a free, beginner-friendly downloadable PDF pattern from Bhooked Crochet, designed to create a charming approximately 31" × 31" [78.5 cm] square baby blanket. The finished piece is assembled from individual crocheted squares arranged in a geometric layout, giving it a modern, graphic appeal that works beautifully as a nursery accent or a cozy wrap for a newborn. Because the pattern is rated Easy, it is an excellent project for those who are relatively new to crochet and want to build confidence while producing a polished, gift-worthy result.

Design Structure: Modular Squares

Rather than working the blanket in one continuous piece, this pattern uses a modular, block-based construction. The blanket is made up of individually crocheted squares that are later joined together according to a provided assembly diagram. There are two distinct sizes of squares:

• Small Squares (make 8): Each small square is worked over 10 rows, building up to 10 blocks of 3 double crochet. Subsequent decrease rows (beginning at row 11) reduce the block count one at a time until only a single block remains, creating the characteristic stepped, triangular or diamond geometric shape.
• Large Squares (make 2): The large squares follow the same foundational construction method as the small squares but are extended further — worked through 20 rows to build up to 20 blocks of 3 double crochet — before the same decrease sequence is applied from row 21 onward.

This modular approach means each square is a manageable, portable project on its own, making it easy to pick up and put down between sessions — a great advantage for busy makers.

Techniques Used

The blanket relies on a small, focused set of crochet techniques, keeping it accessible for beginners while still producing a visually interesting result:

• Foundation chain and turning chains: Each square begins with a chain-6 foundation, with chain-3 serving as the turning chain and as the structural spine of each block throughout the pattern.
• Double crochet (dc) block construction: The primary stitch unit is a group of 3 double crochets worked into a chain-3 space, repeated across each row to build the grid of blocks. This is a classic granny-square-style block stitch technique adapted into a square format.
• Slip stitch (sl st) shaping: Slip stitches are used strategically at the beginning of decrease rows to step inward across completed double crochet stitches and chain spaces, effectively reducing the number of active blocks row by row. This creates the geometric, stepped diagonal edges that define the design.
• Seaming with single crochet (sc): The individual squares are joined with wrong sides facing using a slip stitch join at the corner, followed by 30 single crochets worked evenly through both thicknesses. This creates a neat, slightly raised seam on the right side that can add a subtle decorative line to the finished blanket.
• Consistent yarn shade for joining: The pattern specifically advises using a consistent shade of yarn for all joining rows — the sample used the white section of the variegated yarn — to ensure the seams read cleanly and don't compete with the geometric color pattern of the squares themselves.

Stitches Used

• Double crochet (dc) — the primary construction stitch, used in groups of 3 to form each block
• Slip stitch (sl st) — used for shaping decreases and for moving across stitches without adding height
• Single crochet (sc) — used exclusively in the finishing/joining stage to seam the squares together
• Chain (ch) — used to form the turning chain, the foundation chain, and the chain-3 spaces that anchor each block

Gauge

The pattern specifies a gauge of 12 double crochets and 6 rows = 4" [10 cm]. Achieving this gauge is important for ensuring the finished blanket reaches the intended 31" square dimensions, so sw
