When I start to construct a landscape I first construct what I call my canvas. I look at my photo or drawing and decide what needs to be in the background. Here I have sky and water. I will be adding a middle ground as I progress. If I have a very large middle ground I will add it between the sky and water. Since I have a building that was going to fill the right side of the sky I pieced it with the sky. I had to piece the sky as the fabric I wanted to use was not large enough. You will see how I cover the seam up later.
