I have also seen quite a few you tube videos using vertical paper bag albums and wanted to give one a try. You may remember I did one sort of vertical quite some time ago - It was a matchbook album from February of 2012. Scroll down past the telescoping album to see the interior of these mini's
Well - now to try another style - the ideas is from quite a few locations, the only thing I can say for certain is that I used a Laura Dennison style stack the deck binding. I really like that one and how it lets my pages lay out flat.
I plan to update as more of this album is complete. Supply list and such will be over at scraprageous forums
