Okay, I have to say that I struggled with this one. My first attempt is the top row in the top picture. I just wasn't getting it, clearly. So, I looked at another set of instructions. Sometimes I need things explained in a different way. The green stitching, the bottom row of the top picture shows that I finally did get. I was then brave enough to add it to a crazy quilt block, bottom picture.
