I used egg cartons, paper towels, corn starch, glue and water. Constructed it and then air brushed it in layers, added trees (branches from outside), moss (from hobby lobby, leftovers from a school project) , grasses (leftovers from school project, rocks (from outside), and dirt, sand (outside). Prolly cost about $1, 2 supplies used.
Gonna try ice terrain maybe next!
