How to join granny squares using the zigzag crochet technique

This technique creates a beautiful zigzag pattern when you join granny squares together. The seam is flat and visible, so it’s a good idea to use a contrasting colour. The zigzag pattern is visible on both the front and back. Place two granny squares next to each other face up. Crochet the two squares together using a chain stitch, alternating in the two squares to form a zigzag pattern.
