I am happy to say that I did figure out how to make a secret panel card in one piece and made this birthday photo album card for a friend to record her daughter's birthday with a couple of photos and a bit of writing.
The opened hidden panel . . . it reads "if nothing ever changed there would be no butterflies"
I also covered the back side of the card/album. The layers of CS and DP make this card heavier and sturdy - more like a small book - which I liked. Hope you do too. :<)
Beautiful day here in WI - hope you have great weather where you are also! :<)
