One idea that we have is a "scene" with daisies and sunflowers. The shed with the window, i'm hoping we can tag it with our surname (something trippy, bubble letters or 3D) or whatever else fits your eye.
Each shed is about 100 sq feet. each sheet of aluminum you are looking at is about 3.5x9feet. the shed will be trimmed with wood . one shed is the back and side. the big shed is one side and the front.
Your ideas and having a blank canvas is all your to practice on..
