Today my best friend was visiting and like every year she was begging for some folded christmas decorations. After a long discussion what is possible and what not, we agreed in making some large trains as well as some other things.
Here´s the first train I folded with the kind help of Gerwin and my friend for cutting the paper and precreasing. The starting size of the paper was 50cm x 5m, so the total length of the train should be around 120cm in total. On the one meter ruler on the front of the picture is a one cent coin placed for relation (right hand side):

By the way, the little thingy in the second wagon is a train I folded earlier from 6x60 cm paper...
