Village Field Crops

I've now pretty much finished the painting on the village fields and garden plots, ready for planting some crops on the ones that aren't ploughed. I think I'll cut some strips of the Javis grass mat to make rows of plants for some of the bases but just do a whole rectangle of the grass mat for some of the others. I was also thinking of turning the big base into a wheat field, if I can find something to use as the standing crop, leaving some parts of it as flattened or harvested areas so that I can stand figures on top of it?
