White cotton or linen place mats are an ideal backdrop for a verdant lawn motif.
From a flat of wheatgrass, cut enough blades (removing roots) for one mat. Lay mat faceup over a sheet of white card stock. Arrange 5 to 8 blades along the base of the mat. Lay another sheet of card stock over blades. Hold it in place, and hammer in a uniform manner. Remove top piece of card stock; discard blades. Repeat, working in sections, using fresh grass. Designs will fade over time. Wash with mild detergent in cold water.
