Don't know hat level the scarecrows are for but this can be modified to your
grade. It is for a scarecrow head.
Take a lunch size paper bag. Stuff with newspaper until it "swells" like a
head. Tie or rubberband the opening closed. Holding the bag with the gathered
part at the bottom, Add scarecrow features in medium of choice. Use a fabric
triangle scrap, cut like a bandana, and attach to the bottom of the bag (which
would be the neck). Add a hat of sculptured construction paper, or newspaper.
Embelish with sunflowers that are painted or constructed of colored paper with
real sunflower seed centers. etc.
