Lesson Nine in the CYC Certified Crochet Instructor's program is on finishing techniques, namely seaming and buttonholes.
In This lesson I was required to plan an intermediate class project to teach the mattress stitch, the back stitch, and the slip stitch method for seaming. I decided to use use granny squares for my lesson plans because everyone at the intermediate level should be familiar with the basic granny square and since granny squares are generally joined it seemed like a good fit. The actual joining is done in a contrasting color so the reviewer is better able to see the seaming techniques.

In lesson nine I also had to plan a project to teach button holes which included written instructions and a worked project.
