So here is my set-up: I had two pieces of poster board (I paid under $2 for these) I used a stack of DVDs to prop my backboard up and some double-sticky tape to secure Henry where I wanted him to be. You can see that I raised the blinds so that there wouldn't be any lines in my light - it was a pretty cloudy day so that worked. If it had been a bright and sunny day I would have rotated the blinds so that the light bounced off of the ceiling.
Here is my SOOC shot. I cropped it a little, used Willette's Curves Boost (this is part of her fan freebie set called action basics and is an awesome action - which I use it all of the time) then I cloned out the little bit of seam that was left.
