Here's a little ditty I found on Ravelry.com. Rather than using our dining room table, Joe and I sit at our coffee table in front of the TV and eat dinner. To not scratch up the table, or burn it with a hot plate, I've made crocheted hot pads, but nothing fancy. Just a simple circle. But then I saw this pattern and I had to try it out. So easy and they turned out great! You start with six crocheted rings, then connect them together with a crochet strip.
