So a few of you guys were asking about what kind of paint is used for the terrain. You're actually not painting the different shades of green. The only time you do paint is a dark brown coat once your plaster cloth has dried. Basically you make the grass using different versions of pre-exisiting "Turf" or whatever. Check the picture below.
Basically you take you spray glue bottle that has been diluted with a tad bit of water and spray the dry plaster cloth. You then fill the little sauce cup (That has a few holes in the lid) with your selected prefence of green turf. The turn feels grainy, kinda like salt, but no, kinda like those strings or little pieces of carpet that get away. You then lightly sprinkle your green turf over the area and let it dry. Once it drys you may need to brush off the excessive amount of turf if the need is there. Other than that, that's how you make your green scenery! Easy, am I right or what?
