Trace the cookie boxes onto your cereal box cardboard and cut out. glue a piece of cereal box to the back side of each cookie box (this makes them stronger. They will be your scrapbook covers). Cut construction paper to fit and glue it to the cereal box. Your cereal box cardboard is now "sandwiched" between the cookie box and the construction paper.
Trace your cookie box onto several sheets of white paper and cut out.
Punch three holes in the same place on the top of each cookie box and each sheet of white paper. Make these into a book using the rings or the yarn.
Add troop photos, mementos and decorations to the pages.
I got double prints each time I developed film and took the few photos from each roll that I wanted first. Then, I made an envelope for each girl and divided the photos, putting photos where she was the "star" into her envelope. Each girl got about eight photos and I had a stack left. I told them before they started that everyone does not have a copy of each photo and everyone's envelope was different. Feel free to trade. I spread the extras out on a table and invited them to come help themselves to photos of their friends -- just remember to share. They did REALLY well! Everyone got some of the extras. I also spread out post cards, etc. that we accumulated during the year.
Remind the girls to think before they cut. If they cut a photo wrong, they can't put it back together.
Clean-up is easier if you spread out newspaper on the table.
