Crocheting granny squares is a popular and versatile technique that can be used to create a wide variety of projects, from blankets and throws to bags and garments. Once you have crocheted a number of granny squares, you will need to join them together to create your desired project.
There are a number of different ways to join granny squares together, but the most common method is to use a slip stitch. To join two granny squares using a slip stitch, simply insert your hook into the last stitch of the first granny square and yarn over. Then, insert your hook into the first stitch of the second granny square and yarn over again. Pull the yarn through both loops on your hook and tighten to create a slip stitch. Repeat this process until all of the granny squares are joined together.
