Here's a neat trick. Take cold water and literally pour it over things that you want to preserve (not too much, just like a sprinkle like you were watering plants). It might melt the snow just a little bit, so plan for that, BUT if the weather is cold enough, it will generally start turning into ice, and therefore, preserving your creations longer. :3
