Brontosaurus crochet blanket pattern – C2C baby blanket

Add a playful dinosaur to a handmade baby blanket with this crochet brontosaurus blanket pattern. The large brontosaurus design gives the finished blanket a fun nursery look that works well as a stroller blanket, lap blanket, or handmade gift for a dinosaur-loving baby or child.

Quick answer

This advanced beginner crochet brontosaurus blanket is worked as one continuous corner-to-corner (C2C) piece using worsted weight (#4) yarn and an I-9 (5.5 mm) crochet hook. Color changes create the dinosaur directly in the blanket, and a four-round orange border finishes the edges. The finished blanket measures approximately 30 × 30 inches (76 × 76 cm), and the pattern includes both a graph and written instructions.

What is corner-to-corner crochet (C2C)?

Corner-to-corner crochet, also called C2C, is a method worked diagonally in small blocks made with chains and double crochet stitches. In this blanket, the brontosaurus design is created with C2C colorwork as you crochet from one corner to the other.

Here’s a quick overview of the materials, finished size, gauge, and pattern notes before you begin.

Skill level

Advanced beginner. This pattern uses the corner-to-corner (C2C) crochet technique and includes color changes, so you should be comfortable with basic C2C stitches before starting.

Materials needed

  • I-9 (5.5 mm) crochet hook
  • Worsted weight yarn (#4) in black, gray, green, dark green, and orange
  • Yarn needle
  • Scissors

Finished size

The finished blanket measures approximately 30 x 30 inches (76 x 76 cm).

To make the blanket slightly larger or smaller, you can use a different yarn weight or hook size. Changing the 40 × 40 block layout would require redesigning the graph.
