I have seen lots of people (mostly in the Ali Edwards community) who have being going crazy over the 9" x 12" scrapbook size and many of them have switched from 12x12 Project life to this. It's not something I have seen over here though? I guess it just hasn't caught on as much as it has in the states?
I was intrigued as it still follows the pocket page format Even a quick search of this site has shown it was a thing many years ago (funnily enough I don't remember seeing it myself!) but again I guess because it didn't catch on then stockists stopped selling it.
