oh thank you! I missed that link about. The method is much better than the lasso cut and paste because it is non-destructive and looks much more natural.
The only thing that does not work with the layers mask in PSE6 is when he says to alt+layers mask to add a new, already filled with black mask. It still comes out white but oh well, just go fill it with black.
Thanks so much for sharing this method. My kids are loving it. So far we've done the oldest as his own band (singer, drummer, both guitarists, all with different clothes on), the youngest dressed up like an army man and did a whole battle scene in the yard and we also posed the cat all around the room.
Too fun!
