Thanks everyone for the nice comments! The popsicle is all cookie -- the sticks are a thin layer of candy clay on top of the cookie. For the crevice, I let the frosting set up a little bit and then used a chopstick to press it down a little.
The "cage" of the fan is chocolate. I drew rings of various sizes on waxed paper. After they hardened, I arranged them on a plastic half-sphere and then drew the straight lines to connect them together. I'll try to attach a "side view" picture.
The firefly jar is my fave -- brings back many happy summer memories from childhood. But my husband took one look at it and said, "Yuck! Who would want to eat BUGS?"
