This dragon is made from a 9"x12" sheet of 1/4" foam from the craft store, cut in half (so you can make two, with lots of foam left over for other figures!) The wings are cut from construction paper. I used no glue in connecting the pieces--none is necessary because the notches cut in the foam fit snugly together. For the manga figure, I copied a picture that I'm really embarrassed to say I cannot find again. But you can make any figure stand up, if you leave 1/4" extra foam on the bottoms of the feet, then cut holes in a square of foam and insert. Another option is glueing a small bit of foam behind the feet to prop the figure up then glueing on the figure. I used acrylic craft paint for the dragon, and washable marker for the manga figure. Both work great on foam. So does water and chalk pastel!
I made these cute little guys out of a 9"x12" sheet of 1/4" foam from the craft store, cut in half (so you could make four Dinos out of one sheet.) This foam is marvelous for making 3-D "puzzles" by cutting notches in each piece and sliding them together. You can also make these from corrugated cardboard or cereal boxes. (Card stock tends to be too flimsy.)
