While it is true that Thanksgiving cannot occur until every preschool child completes at least one handprint turkey, there is a cornucopia of non-turkey crafts that are often overlooked.
Corn painting: Need to occupy the kids for awhile? Buy corn still in the husk and let the kids shuck it!
Pumpkin pie: Major points for simplicity. Paint or ripped paper work or you could use both! This also sets up well for a fractions lesson if you use a whole paper plate and then cut it into slices.
Woven placemat: Best parts - No paint or glue required and no laundry or dry cleaning when something inevitably gets spilled.
