Guess it's too late to join this challenge, but I'm following along and trying this too. I have a couple of questions since I'm relearning how to do this after several years of inactivity.
I'm using PSE 8:
When I tried to flip my BW picture, it flipped my color one too despite the fact that I was on the BW layer. Is there any easier way to do it? I had to drag it to a new file, flip it, and drag it back.
Also, how do you cut the photos in strips like that??? Someone was talking about a template, but I don't have one like that. I'll play with this and try on my own, but your all's help would be appreciated.
