Bible town set. We used the "stable" from our Christmas Nativity scene as the main house. All other houses were sheets of cardboard. Background is Oriental Trading's "Sky" backdrop. Plants were borrowed from other areas of the church building.
Here's an idea - fake hay bales made from cardboard box. This one coated in rafia (about 5-6 packages from Dollar Store), glue-gunned on. Also suggest strips of paper, glued on, painted to look like straw. Whole thing folds up for storage (like a cardboard box).
