Over the past year I have made several afghans. The last one was finished yesterday using a different color of left-over yarn in each row. I don't plan to buy any yarn for a while and just use more of the parts of skeins.
I did happen to see a free pattern for a pot holder that used a new (to me) stitch. It's a single crochet made in a different manner that makes a very thick layer of yarn. No lining necessary nor a double layer sewn together.
So here is the beginning of the new project.
