A perfect lawn

Hi guys, seeking the experts advice once again. How can one create a lawn effect on stage, without spending squillions on artificial turf? Note: Said garden scene is placed directly after the interval so there's set up time available (20 minutes), however on the other side of the scene, there's only a few minutes to clear props etc, including: garden bench, fake plants etc... the stage is jarrah stained floorboards. Can it be done? Lighting? Second question. I like the idea of using free standing lattice as screens, does anyone know where this can be hireed . purchased cheaply, or would it be better to paint a mobile flat? cheers Johnny Grim
