These centerpieces are great for the Fall wedding season! Use natural elements like leaves, pinecones, and twigs to get this effect! (To make sure the leaves don't brown, you can get fake ones from craft stores and spray with a fire proof spray!
I would've never thought of it, glad someone did. Fall pillows made from inexpensive placemats from Walmart. Rip seam open a little, stuff them, and sew up edge. Not sure I'd make fall leaf pillows, but this same idea could work on other placemat shapes.
