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.
Just take a metal clothes hanger and bend it to make a circle and then tie the ribbons around it. looks like a simple knot. then you can use the hook part of the hanger to hang it up :) so cute for the girls bedroom door
