Here's a classic that I've made many times. It's a little too "open" to be a heavy duty pot holder, but I often use these for pan handles that don't need a lots of padding to be moved. In addition to dish cloths these can be also be used as pads under warm dishes. I am sure I have used them for all three purposes over the years.
This is a great "teacher" pattern for a project with someone who wants to learn to crochet, especially the kids who may be home for a snow day. It's quick, relatively easy, and makes an item great for them to use themselves or give as gifts. I've made several sets of these this year to use as hostess gifts, too. I have another teaching pattern coming, too, as soon as it is finished and photographed. ;)
The pattern is below if you'd like to make some.
