I love the look of these River Rocks used as a pot holder. This is a super quick and easy craft that will last a life time and it fun to make. All it take are the River Rocks that you can buy at most craft stores, some felt or cork board and hot glue. If you get the right rocks then you can set hot pans on them as well as anything else. You could make pot holders like these, or make them smaller and use them as coasters. Cut the felt/cork board in the shape and size you want, glue the rocks down in the pattern you want, let it dry and Enjoy!
