"I bought these notebooks as crafts and favors for my son's dinosaur birthday party. The kids will decorate their "field journals" with foam letters and dinosuars. While I think the kids will enjoy the craft, I'm glad I bought extras. I bought 3 sets (36 notebooks) and at least 8 can't be used. They are pock-marked, have ripped edges, are dirty, etc. Also, the thickness of the foam varies -- purple is very thick (nice!) but the red is very thin (almost like paper). The paper inside is lined, but only on one side (though you can see the lines on the other side). One pack had only orange letter sheets, and the other two had different color sheets ((two red, two orange, two yellow, etc). Also. like the other person said, only one alphabet per sheet, so kids who have double letters in their names will have to share to find all their letters."
