After making this photo featuring the shadow of a wine glass, I decided to make a photo that displays a wine glass with several shadows. The photo shown below is the result of that thinking.

Process
I and probably most studio photographers usually set up a scene before setting up its lighting. Because the core of my vision was the composition of the wine glass and its shadows, I took the very unusual approach of mostly setting up the lighting first; the initial tabletop and background were so plain that they served no purpose other than to support the empty glass and to display the three shadows. Once I decided upon the composition of the glass and its shadows, I tried several tabletops before settling on the final one. Now that I knew I could leave the glass in place, I added the wine and was pleasantly surprised to see the roughly horizontal, striped reflections of it in the background. Last, I added the translucent paper in front of the original background to add both color and texture that complemented everything else in the scene.
If I was a good designer, I would have been able to envision the scene before setting everything up. I'm not, so this process, which was most definitely the reverse of my normal process, worked because it allowed the scene to evolve one step at a time.
Setup
The tabletop is gold, highly wrinkled art paper. The background is gold, translucent, textured art paper hanging about 1/2" in front of off-white art board. The art board in the rear reflected the bright light that created the mostly dark tones that define the outline of the transparent wine glass. The art paper hanging in front of it added color and texture to the background.
Two flashlights of the same model set to their lowest power were on the tabletop on the left front and right front area of the subject. They created the shadows on the far right and left, respectively. A third flashlight of a different model was in between the other two flashlights slightly on the right front to create the middle shadow. It was fortunate that the reflections of the three light sources in the wine glass were located where they could be easily eliminated during post-processing; if they had been located where it would have been difficult to remove them, I might have had to move some of the light sources, which would have changed the position of the shadows and, thus, that important part of the composition.
