Great for a mini album on it's own or add it to a 12x12 page layout to hold extra photos or journaling. (for me they're great for hiding my super ugly handwriting on my layouts)
I'm gonna use them as extended Christmas cards. Use up all me littley scrap pieces of paper (yeah right, i will go and buy more paper...) and wow the fam with my super cool Christmas cards. I might even include a yearly round up letter and pop it into one of the pockets. Gee, this idea just gets better and better!! Will go and think about it some more.
