Thanks Lisa Frase (JJCV)
"I made a bunch of pockets with 6 x 6 scrapbook paper. Each one has 3 pockets (the one centered has little papers in it to demonstrate). I played with my edge punches & decorative edge scissors. In the end, I think the scissors are the easiest to use. You could embellish & add ephemera. It also fits a teabag.
1. Fold a 6 x 6 paper triangular leaving one half inch.
2. Fold again leaving about one half inch.
3. Glue the edge (I used paperclips to until it dried).
I’m building a happy mail stash."
I then cut the corners at an angle.
I used double sided paper, so the middle layer is different than the rest.
