Here's a quick and easy mini scrapbook that also makes a great gift for grandma.
You can make these as big or little as you want simply by adjusting the measurements.
The end product of this one is 4X4. I started with an 81/2 X 11 sheet of paper and cut it down to 8X8. I used an envelope flap for a template to make the closure.
Since I had so few pictures in this one I didn't have to worry about it not closing but you could add an extra fold along each edge so you could put more accordian folds in it.
You are going to want to decorate the front before mounting your picture in though, especially if you're planning on used brads, eyelets, or anything like that.
This is simply tied shut with gold cord but you could get as fancy as you'd like.
I have pictures on both sides of the accordian fold.
You can make these using a theme (all halloween or all christmas, whatever). They're quick and they mail nicely!
