If you are making a model for a school project or a train set, you can make the model look more appealing and beautiful by adding on walls that looks like real rocks. You can make a fake rock wall with a few materials that can be found at a craft supply store, such as plaster of Paris and textured paint. Once finished, you can place the rock walls into your model to make it look more realistic.
