Who doesn’t like to ride the train? Probably there are none. And here to recall all the sensations, you can try to add a picture of the pieces and get the train as a result. But remember that this will not be as easy as it seems. And if you try to start all over from the edges, then you really will have a frame, and then start filling in the edges, and then you will get a beautiful picture in the end. Good luck with you.
