Yep, that was the wrapping paper. Their notebooks are probably 5x7? Mead journal/notebooks. I'm guessing my youngest dd (5yo) wont really 'get it', but she always wants to do what her sisters are doing. This way they can all Smash together.
I was worried that Abby wouldn't like it, or would find it difficult and give up on it, but she's already used up her glue stick. She loves it. Before she went to bed tonight she told me she was going to do her Smash album first thing in the morning. She bought some stickers today to use in it.
