How about making throw pillows? Or lumbar pillows?
I have made pillows out of down. I not only made these pillow covers, I made the pillows also. Out of the down from an old comforter. What is nice about making your own is it can be just the size you want.
How about make a big dog bed?
You could make a new cover and use them as floor pillows or cushions.
You could stuff new pillows!
Make smaller pillows
