I had to make one more fabric backdrop (for a different show this time) and I decided to take pictures as I went, so if anyone is interested, here is how I put together the picture. I have almost no formal training in either art or sewing, so it is a rather haphazard process. I make a rough sketch of what I want it to look like. I pull out TONS of remnants of fabric off my fabric shelf and start moving them around and putting them next to each other. I work on a layer at a time, sometimes starting at the bottom, then jumping to the top and trying to keep everything in some sort of perspective. In this set of photos, you can see how I add parts of the picture, sometimes change my mind and eventually, end up with a backdrop!
