You can do it! I had never done them before either. I have now made 3, my test one 5 layers and 2 more 6 layers. I'm having too much fun
There is no stipulation on shape and layers etc. the only rule is it must be at least potholder size, or if you go smaller, you must make 2. It does not need to be made as a potholder. It can be a table or wall decoration. And it should be something you would like to receive. (I don't really need to say that, you guys always blow me away!)
