If you're relatively new to it, keeping the background flat and wrinkle-free works best with most of the software. For our 2012 Puppy Calendar, we actually had it draped over a chair so we had lots of shadows but Linda was able to cut the pups out regardless. As they say, "don't try this at home. These people are professionals." As I said, if you're using software other than PhotoShop, keep it as flat and fold-free as possible.
