As all of the other posters have said, practice is the key. And it won't be pretty the first few times you attempt it, so don't start on anything of value....try practice sandwiches about the size of fat quarters at first to just get the hang on what you are doing. I know I am my own worst critic and do lots of ripping when I really don't need to. Remember to have fun and keep at it, even when you think you will never get it!
