Felt Leaf Pillows: "This project can be completed using a store-bought pillow cover, but a flat piece of fabric works best, as it fits easily into a sewing machine. After you embellish the fabric with leaf patterns, you can use it to make a pillow cover.
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.
