I have a whopping seven done. I've enjoyed trying to work the passport into my "normal" way of scrapping. It's making some of my pages have a different style than my usual and flipping through them (before I get to printing them), I've decided it's not a bad thing and I'm keeping them.
I've also been working the Summer Getaway challenge. I've only used one as double duty for the passport because I'm TRYING to challenge myself to keep them separate.
