This is the final part in my series of patterns to make a life-sized anatomically-correct human brain. I have tried to make it was accurate as possible to the gyri and sulci in a real brain. The blood vessels are optional.

You will need:
A 2.5mm crochet hook
3 balls of anchor creativa fino 4ply cotton in pink
Polyester toy stuffing
Red #10 rico essentials cotton
20-30 safety pins
Crocheted inner brain structures (optional)
around 20-30 yarns scraps of varying colours
