Here are the steps to crochet granny squares together:
1. Start with two granny squares that you want to join together. Place them side by side with the right sides facing up.
2. Thread a yarn needle with some spare coordinating yarn. Pull the yarn through and tie in a knot.
3. Insert the yarn needle under the outer loop of the top of the stitch on both granny squares. Bring around and insert again all the way down the square.
4. Create the row first and then sew rows together.
5. Repeat this process until all of your granny squares are joined together.
