Each unit is made with a V or valley folded index card and a W with two valley folds and a mountain fold in the middle. I stamped a background on the V page and added one of my soul collage images. Then, I wrote a journal entry about my soul collage image on the W page and cut a diamond shape out for a window. The W page is then glued to the V page and five V-W units are glued together back to back.
Looking from the top, the V-W units show up better- three in front and two in back.
You can also make this little book with postcards. It's a great memento of a recent trip.
