Removing Backgrounds - its all about edges

If you look closely at the photos in my previous post you will see that one of the dolls has a doll behind it. I was using it to prop up the doll so I could photograph at the right angle.

Yes I spent many an hour trying to get the doll removed from the background and the background to then match ones from other images. In the end I almost got it with the colour but I had to accept that I didn't have enough time to fix the edges against the dolls arm. So it was back to the drawing board and looking for another image that could work.
