Halloween/Fall craft ideas for kids

Anyone have any cute craft idea for kids that can be made out of things already in the house? I have to babysit my cousins tomorrow (7 and 10) and was thinking of things to do with them. We may bake cookies and decorate them or make pom pom creatures as pencil toppers. Any other ideas?

I accidentily asked this on the newlyweds board too. Sorry for the redundancy!

you can make cup cakes, and to make a spider web on them,,,take black decorating gel, and make circles, 1 inside the other. then using a tooth pick, start in the center and drag it out.
