I was a bit stumped about making a train. Then I remembered that I had bought some plastic mesh canvas. I cut out the sides and ends of each of the cars and sewed felt to it. I thought about using buttons for the wheels but worried that they might pull off, so I made the wheels out of grey felt. I used an empty thread spool for the engine and covered it with black felt. I attached velcro between each car so that the train would stay together when it was pulled. I sewed bias tape to the bottom of each car so that the elastic could be threaded through it and the elastic is sewn together on the back of the felt background. Eventually the pages that back each other will be sewn together around the outside edges so the sewing won’t show. The train isn’t beautiful, but it does move on the elastic along the short track.
