Thank you sirs, for the kind words!
Moonman- the mud itself doesn't stick to the foam that well. I had a few spots of just bare foam and it didn't seem to want to hold. I'm sure that I could go back today and add another coat over those areas, since the light coat has dried, but those spots are in the back. The plaster cloth over the foam did a good job of conforming and taking away all the rounded shape left by the foam.
If I end up doing this again, I think I'm just going to use the paper towels dipped in plaster, to save a step in this process!
