Brontosaurus crochet blanket pattern – C2C Baby Blanket

Looking for a fun dinosaur blanket to crochet for a baby or child? This brontosaurus crochet blanket pattern is a one-piece corner-to-corner (C2C) design that features a large brontosaurus worked directly into the blanket. It’s an advanced beginner-friendly project made with simple stitches, easy color changes, and a playful dinosaur theme.

How this brontosaurus blanket is made

This blanket is worked as one continuous C2C design, rather than separate squares or panels. You’ll start in one corner, increase to the widest point, and then decrease back down to the opposite corner.

As you work, color changes create the brontosaurus design directly in the blanket. After the main blanket is finished, you’ll add a simple border around the edges.

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.
