How about a wreath with local dried flowers and foilage. They wouldn't have to be big and grapevine wreaths are pretty cheap. I used to do wreaths when I did shows using hemlock cones, pine cones, peach pits, cinnamon apples that I made, acorns and wheat. Then I would add a miniature scarecrow pick and bow.

You could also do little baskets with miniature cinnamon apples and rag homespun "ribbon" or raffia or Pinecone firestarters that are dipped in parrafin.

This may be too late for you, but you could collect seeds from open-pollenated annuals (or even perennials) from your group's demonstration garden, and/or everyone's own gardens and put them into large containers. (Be sure the seeds are dry!) Obviously you would not have to clean the chaff from the seeds as meticulously as commercial seed houses.
Allow "customers" to use a small spoon or scoop to take what seeds they might want, charging per scoop. Have available small paper envelopes (you can get nice sized ones from hobby stores that sell materials for stamp collecting, etc., or some office supply stores), giving the common & botanical names and the date. Some of you could make up separate sheets beforehand on which are written brief cultural directions for each flower, then cut apart the strips and offer them alongside for those who need that info. Have writing implements available as well as clear tape to seal the envelopes with. Might sound time-consuming but it's really not--and think of the opportunity for all the volunteer hours you all would accrue! CK--an MG from PA :-)

I made refrigerator magnets out of denim jean pockets (kid size) and added silk fall flowers but you could just as easily use dried pods, leaves and dried grasses. Added some tiny apples, punkins, and a raffia bow. Also laminated some cute fall graphics and glued them to popsicle sticks and inserted. I used the strip magents on the back...

How about some small scarecrows on stick things for flower pots. A small scarecrow face made with dried poppy seed pods or somthing similar. Hot or cold glue a pin on the back for wear. Hot glue and as soon as it is cool it can be worn. Have fun.

I saw a neat craft that involved covering styrofoam balls with potpourri or dried herbs - they were pretty in a big bowl, and smelled good, too. Cindy

Thank you for all of your suggestions. The committee took a slightly different turn in the end. We did demos of topiaries made from pumpkins (from Lowes magazine) and for the kids there was an audience participation story about building a scarecrow. Will keep your kind contributions for another time. Thanks, again.
